Additional information

Weight 6 lbs
Dimensions 13.75 × 12 × 4.5 in





PREAMP – all solid state analog design with integrated soft clip circuitry.

  • INPUT– 1Meg ohm input impedance
  • CHANNEL OVERVIEW – Voiced to provide natural, pristine, transparent reproduction of the bass instrument.  The circuitry consists of an FET feedback type variable gain circuit that provides wide range, continuously variable gain for use with a wide range of instrument pick-ups and preamps.
  • CONTOUR — continuously variable control of 2 vastly different response curves. In either CURVE position, when the SHAPE control is all the way off (CCW) the response curve is completely FLAT.
    • Curve A (Blue) — a variable pre-shaped curve that boosts lows and highs while simultaneously cutting mids.  The slopes are fairly gentle which keep the tone shaping very musical.  This curve covers a wide range of sounds from flat to classic to modern depending on the position of the SHAPE control.
    • Curve B (Amber) — a variable pre-shaped curve with attenuated high mids and highs, a low mid bump, and a slight roll-off of the lowest bass frequencies. Again, the slopes are fairly gentle which keep the tone shaping very musical. This curve is intended to provide sounds in the range of vintage amps and vintage cabinets that do not have tweeters.
  • ACTIVE EQUALIZATION – The MAGELLAN® 350 contains an active 3 band equalizer with a sweepable parametric mid-range frequency control.
    • Bass   +/- 15dB boost/cut shelving curve with a corner frequency of 75Hz
    • Mid      +/- 15dB boost/cut of the variable mid frequency selected
    • Freq     Variable mid frequency from 150Hz-3kHz
    • Treble   +/- 15dB boost/cut shelving curve with a corner frequency of 6kHz 

POWER AMP – The MAGELLAN® 350 uses a state of the art, class D power amplifier design and a high frequency auto-sensing universal switch-mode power supply (SMPS) to achieve unprecedented high performance and lightweight packaging. There are no Voltage Switches to change or jumpers to move. This SMPS senses the line voltage from 100-240 Volts and automatically configures itself.


  • XLR Direct Output –
    • Mic / Line Switch
    • Pre / Post EQ Switch
    • Ground Lift Switch
  • Aux Input
  • Head Phones
  • Dual Speakon® Speaker Outputs

    Okay so, I’ve had the MG 350 for about two weeks now. I’ve been playing out of a single high end 112 cabinet. I must admit that I’m still experimenting with the diverse tonal variations. So far, this amp has not only met my expectations but has exceeded them. The wattage is more than sufficient for my needs and that is just running a single cab. Soon enough I will be getting another 112 cabinet and will be able to run the full 350 W. The contour and the three band EQ are very sensitive to even minor changes which is great for expressional dynamics and dialing in that sound you’re looking for. Jeff was great to work with and it was a pleasure to do business with him. Thank you!

    For years I played through a SWR Super Redhead and swore it was the best all around combo. While it served me playing for many worship teams for many years, I sold it to a friend who needed it more as I had to stop playing when my daughter was born. What the heck man, get to the point. So I have not a fretting in my life, only smooth fingerboards…and between my 5 string acoustic bass and my EUB (especially when played arco) very few combo amps I have played can hang. An bowed low e farts almost every reasonably priced combo I have tried, till this. I was at Chuck Levin’s Washington Music Center trying out various EUBs and saw the MG 350…I tried it, and immediately was blown away! At 1/4 of the size and weight, and 500 dollars cheaper than my old beloved SWR, the MG350 sounded so much better (so that is what they mean when they say transparent). I brought it home, and knowing if I start playing in worship teams again, I can add the second speaker if needed. Seriously folks, I am running the volume and master at 9 o’clock and it is plenty loud! I have played with the various settings and am impressed of the simplicity of operation, to dial in various “color” to the sound. So whether I am bowing away, walking, or slapping, this combo is absolutely INCREDIBLE! The handle it perfect, making schlepping this thing a breeze, and it really allows the personality of each instrument to come through. Mr. Genzler, sir, you and your team have done it again!! Thank you!

    I bought this amp as a combo with the ba10-2 can and it is amazing! I originally bought it for smaller gigs and to use with my upright bass. I’ve played through ampegs, gks, fenders, and acoustic images and this amp blows all of them out of the water for upright bass tone! I used to use an ampeg b4r as my main gigging amp with my electric bass but the Magellan 350 sounds so good that I ended up buying a second ba10-2 cab and running this as my main amp for any occasion. The a/b contour and mid frequency dials allow you to achieve endlessly unique tones for whatever style the situation demands! Jeff Genzler’s customer service is as top notch as his products and I definitely recommend Genzler Amplification to all bass players!

    Here are my thoughts of the Genzler Magellan 350 bass amp after having gigged it for the past several months. I’ve deliberately left it a while to make sure that the honeymoon period was over so that any issues or quibbles that I may have with it have become apparent. For reference, I play in a 5 piece, female fronted, rock, pop and party band playing a mixture of pub and club gigs as well as some private work and functions. My cab is Tecamp M212 and I use a variety of basses, usually with a bias towards the neck pickup. I play finger style more or less exclusively and am pretty heavy handed too, I love to dig in when I’m playing!

    If you’re not already familiar with the amps here’s what Genzler themselves have to say about them, the Magellan 800 and the Magellan 350. When I originally bought the amp, I tried it against some of its peers. To see how I thought it stacked up at the time see the thread here.


    The 800 amp has both a transparent clean channel (that can be coloured by the Contour control, more of that later) and a coloured Drive channel. That makes it extremely versatile and usable for pretty much any and every musical situation that you’re ever likely to find yourself in from soft jazz to the lesser extremes of metal.

    Clean channel

    The clean channel with the eq set to noon and the Contour control dialled out sounds even across the frequency range, there are no peaks or troughs in the signal. This sound works great in the mix straight out of the box. The Genzler marketing talks about a “weighted feel to the notes” and this is absolutely correct, the low end is definitely forceful, punchy and powerful but without being overbearing. Those that claim that class D amps lack heft should take an objective, unbiased listen to the Genzler.


    The EQ frequencies that the Magellan uses are absolutely perfect for real world live use. The bass EQ is voiced at 75 Hz which is great for adding audible bass to the sound if you’re in a room where the bass is sounding a bit thin, or for backing the low end off if things are booming on stage. In my experience this has proven to be a far more useable frequency for controlling your low end than 40 Hz that many other bass amps use.

    The semi-parametric mid covers a wide range from 150 Hz to 3 KHz. It sounds perfect with the mid eq control at noon, which keeps things flat but I personally like to give it a slight push in the upper mids to help the bass cut through a busy mix. But you have massive flexibility here to control those critical mid frequencies whatever you want to do with them.

    The treble is voiced at 6 KHz so is useful for adding some presence to the tone or brightening up dead strings. Or backing things off a touch for a great retro tone. The treble never gets harsh and the tone is never completely dulled when the top end is backed off.

    The simplicity of the tone stack and the choice of frequencies that they operate on cannot be praised enough. The Genzler just delivers everything you need and nothing you do not.

    To finish of the awesome eq section there is also the dual voiced Contour control. A button on the front panel allows you to choose between curves A and B;

    Curve A is a mid-scoop pre-shape. However, compared to similar controls on other amps, this one is more gentle and is more usable because of it, it is usable throughout most of its range. Its only when its cracked beyond about 3 o’clock that the bass sounds like it could potentially to disappear form the mix.

    Curve B bumps the low mids while rolling off the upper mids and the extremes of the frequency range to give a great retro vibe or to tame a bright sounding, scooped rig . As with Curve A, things are still kept subtle and musically usable with this control throughout its range.


    There is no mention of any form of high pass filtering by Genzler, but I emailed them to ask about it and none other than Geoff Genzler himself responded to say that;

    Yes, we do utilize a High Pass filter with the MG-800. It is a very steep slope and set low around the 30 Hz range. This allows us to achieve a clean, solid and authoritative low end without potential flubbyness. This also helps with protection from over-excursion for speakers under high power situations.

    I hope this information is helpful.

    Best Regards,

    Jeff Genzler

    How’s that for customer service???

    Construction and finish

    The amp is a great looking design IMO and the quality of construction is flawless. Genzler describe it as; aircraft-grade, brushed aluminum (sic) chassis with a sleek custom extruded front panel. It certainly looks classy and feels substantial. Anyone concerns over quality because it was built in the far east are misplaced. And it has 4 ultra-important blue LED’s on the front panel. Nice.


    As you have probably gathered by now, I’m struggling to find fault with the Genzler Magellan amps. However I do have a couple of very minor criticisms. It’d be great if the Contour voicings were footswitchable so you could switch between the different curve options on the fly. But this is just nit picking, and not something that I’m likely to ever do anyway.

    And then there’s the name. No doubt there is a reason or story about why Magellan was chosen, but it just seems a bit of a daft name for a bass amp to me, It’s more like a name you’d give to a dog!


    Honestly, I can’t fault the Magellan amps. Everything about it is just right. It delivers everything you need in the real world. I’ve played many gigs in many different venues with mine and I’m yet to get a bad sound out of it or have ever been in a situation where the sublime eq section wasn’t able to eq the bass to a room with poor acoustics in a matter of seconds.

    In fact, I like it so much that I bought the baby 350 model as a rehearsal and back up amp. The 350 has the same great tone and features of its big brother but it does lack the jaw-droppingly brilliant drive channel. However is makes up for this by being smaller, lighter and cheaper. I’ve also gigged the 350 and don’t let its nominally low power rating put you off, this thing has more volume than you’re ever likely to need on a typical pub, club or function gig.

    An update to the original review after a year of gigging the Magellan’s.

    I’ve been gigging both the 800 and 350 for around a year now and have played some 40 or so gigs with one or the other of them in that time, as well as numerous rehearsals. The honeymoon period is well and truly over now and any flaws in the amps have had time to makes themselves known …

    … Except they haven’t. I still cannot fault these amps in any way, and I still stand by everything I said in my original review; They are infinitely flexible and can very quickly and very easily give you any bass tone you’re ever likely to need (with the exception of very high gain distortion). The pre-amp is so simple and intuitive, and the EQ points are set exactly where you need them in a live situation to allow the bass to cut though a busy mix. The DI is noise free.

    The anti-Class D league will have you believe that lightweight amps means lightweight tone. That is simply not the case with the Magellan’s, there is a real weight and depth to the tone.

    Although I prefer the 800 purely because of the drive channel – which I still cannot praise enough – be assured that the 350 is more than up to the task of gigging alongside a noisy drummer. In short these are simply brilliant amps, everything about them is just right.

    I was using a GK RB700 but the weight was too much and the amp simply more than I needed so I picked up a GK MB200 – which was adequate for jazz gigs but could not handle the volume for R&B and fusion. As is the current rage amongst bass players, the Aguilar was my initial thought. I did my research and was wanting to play through the Tonehammer 350. I called around and none of the dealers had this model in stock. In searching for ‘Authorized Dealers’ on the Aguilar website I discovered “Bass Club Chicago,” a store I was not even familiar with. Anyway, I gave them a call and they had all 4 models of the Aguilar in stock. So off I went, with every intention of purchasing the Tonehammer. Upon plugging in, I was immediately underwhelmed. Indeed it was an improvement over the GK – as there was more watts, but the tonal shaping was not all together dissimilar from what I was using. Nonetheless, I was about to make the purchase when I asked one of the owners’, Jeff if there was anything else I should consider, and he suggested the Genzler. Full disclosure, I am not a full time musician, however I have maintained a career in the music industry for my entire life, but was not at all familiar with the Genzler. I plugged it in and the tone, and tonal shaping possibilities were exactly what I was looking, searching and hoping for. I have played 1 gig with it thus far and each of the guys in the band complimented my new sound. It responds to fast runs, each note is more clearly defined, and the tone, for the modest investment and weight, in my opinion is far superior to the Aguilar.

    I could not be happier with my purchase of the Genzler / Magellan 350 bass amp. Thanks Jeff!

    I was working with the Bass Gallery on Chatahoochee Ave Atlanta GA, but they have closed down. I had ordered covers for my Magellan 350 combo and the additional cab 2 – 10, but have lost contact with them, they had them on back order. The staff there was very informative and helpful, and although had had various choices I choose the Genzler product for their big sound and the weight of the cabinets. I like the ability to add cabinets as necessary, depending on the size of the room and what coverage is expected of my rig.
    Can you help me with the covers for my combo and additional 2-10 cabinet ?

  7. Stephen Civitello

    The MG 350 is a great amp. Super clean and a variety of tones are at your fingertips. Very powerful for its small size. I run mine through two Mesa subway 1x12s and it’s the perfect combination for me. Both contours are excellent in helping you dial in that prefect tone you’re looking for. The best amp I’ve owned to date and I’ve had a bunch over the years. Great job Jeff. Thanks for helping me get that sound that’s in my head.
    Keep up the great work Genzler.

  8. Lenny Jordan

    Bought the 350 head with one 10 array cabinet. I mostly play at my church, so small gigs. But now I am seeing that this is no small sound. I like the fact that it is a simple working amp, for me I set the EQ straight up with a little reduction in the mids and then use the contour for adjustments to fit the room. I have probably played everything out there and this is about the best sound I have had in a long while. I like SIMPLE and this hits the mark.
    I think there is that statement “KISS” and Jeff did. Jeff was also very helpful when talked with thru TALK BASS – thanks for the help and the Amp.

  9. Richard Simon

    Long a fan of his Shuttle series of amps that proved to be such reliable workhorses, I am happy to report that Jeff Genzler has re-entered the race of light-but-powerful amps, and has a winner with the 350 Combo.
    Alone, it delivers what seems like more than the stated 175W; with an additional cab, it fills a good-size room.
    As an upright-only player, I couldn’t ask for a cleaner, warmer or more responsive sound than what this 350 Combo delivers. Whether in a piano/bass duo or hard-bop quintet – I’d put my money on Genzler!

    In all honesty, I’ve only had the chance to use the Magellan 350 once since I purchased it in December 2017. My band had broken up when I bought it and will be getting a chance to use it now on a regular basis next month. The gig I did use the 350 Magellan on I got a chance to play through it for 2 sets and have another bass player play the other 2 sets.I used the Genz-Benz Neox 212t with the head.So this the first time I’ve used a Jeff Genzler product whether it’s a GB or Genzler. Ok let’s get to the Genzler Magellan 350 head.It’s nice and lite, simple to use 3 band eq. with a contour control.I ran the preamp gain on 4 with the master on 5. I had the contour on A on full. Treble Bass and Midrange controls I ran all flat(in the middle).I’m using CIJ Fender 75 RI bass.I’m an old school player, fingerstyle no slap and pop, no pick. Soundwise it’s great the head was so simple for me to use.I’m basically plug in and play type. The GB Neox 212T cabinet sounded great, nice tight bass response kind of midrangy and not boomy that you get with other bass cabinets. I also have a Genzler Magellan 112t that I haven’t even tried yet. I can’t wait for that. Bass players do your self a favor a go try the Magellan 350 head.You will not be disappointed.

    Recently I added another 10-2 cab to my Magellan 350 combo. The combo has been one of the best gear purchases I’ve ever made—I love its tone, it has more than enough power for my current volume needs and it packs a punch for its size. There was nothing lacking. But I was curious to explore more Genzler products and I’m glad I did!

    Adding another 10-2 gave me even more of the fullness and smooth clarity that I already love. The heft or weight to the note is almost three dimensional in feel! The stacked cabs provide greater vertical dispersion and I can hear my 5-string fretless even better. I love being able to hear the character of my bass’s various pickup combinations so cleanly and distinctly. This combo stack doesn’t hide a thing and I know it’s helping me become a better player.

    I cannot say enough good things about Jeff Genzler and his products. When I started looking into another cab he helped me make a choice that was best for my goals and playing situation. I am thankful to own high quality gear from a great company. In the future I won’t hesitate to explore more of what Genzler has to offer!
