GENZLER® AMPLIFICATION proudly announces the addition of a second pedal from the “redux collaboration” that brings Jeff Genzler and engineer Andy Field back together again — developing a new line of bass & guitar effect pedals under the Genzler Amplification brand.

And now, the re/Q — DUAL FUNCTION EQUALIZATION pedal is a versatily and expressive tool for use with a variety of instruments, bass guitar, acoustic and electric guitars.  This “swiss army knife” offers 2 specific and separate filter networks, HPF and LPF filters with on/off switching and a 5 band EQ network, with its own on/off switching.   This all makes the Re/Q pedal an essential tool for enhancing an instruments tone or cleaning up room dependent issues for optimal performance.

And the re/Q provides an EQ Output level of +/- 9dB. This versatile design allows the pedal to be used as a clean boost in some applications, and is a great combination with other GENZLER pedals —- the 4 ON THE FLOOR, and CLASSIC BASS OVERDRIVE pedal.   This pedal also offers another level of versatility as it accepts nearly any power supply; 9 – 18 Volts, either polarity. (Power supply not included).


SKU: RE-Q-PEDAL Category:


The re/Q DUAL FUNCTION EQ PEDAL is a low noise, ALL ANALOG multi-function HIGH PASS FILTER – LOW PASS FILTER and 5 BAND EQ pedal that gives the player complete tonal control over the cut-off of the extreme low and high frequencies, plus 5 bands of peak-dip equalization.  The filter section is foot switched independently from the EQ section, and there is additional make-up gain or cut after the EQ for balancing of levels or to act as an additional boost/cut function when the EQ is switched into the signal path. The re/Q is also a great companion to our 4 ON THE FLOOR Classic Overdrive Pedal.  It can be used to tailor your instrument’s tone for various overdrive settings, or increased boost levels for any of the Overdrive gears.

There are a wide variety of uses for the re/Q and is an excellent compliment to either of our MAGELLAN 350 or MAGELLAN 800 bass amps and our Acoustic Array PRO and MINI acoustic combos.

    The re/Q has exceptionally well thought out frequencies, they work wonderful for bass and guitar both. The proportional Q and Q/frequency relationship really works well, it’s almost impossible to find a ‘bad sound’ from re/Q. In some cases I only use the HPF/LPF filters and then tease out just a tad of EQ, or forgo the EQ altogether when just filtering will do the job. The filters alone are quite useful. As well, I have been running reamped vocal tracks through a tube drive recently, and the re/Q makes a potent front end to shape the frequencies that are then saturated.
