Genzler Amplification re/Q

The Genzler Amplification re/Q is a dual-function equalization pedal for bass and guitar, and the second pedal in Genzler's bass pedal line. It puts two separate tone-shaping networks in one box: a high-pass filter and low-pass filter pair, and a five-band graphic EQ, each with its own on/off footswitch so you can use either or both at once¹². RockBoard's PedalPedia calls it a "swiss army knife" of tone control¹. Premier Guitar reported its launch in October 2021, with shipping from mid November 2021 at a USA MAP of $244.99³.

A dual-function EQ: filters plus a five-band network

The re/Q's two halves are independent. The filter network gives you a high-pass filter and a low-pass filter with on/off switching, letting you trim sub-bass rumble below the fundamentals you want and roll off treble above the range you use. The EQ network is a five-band graphic with its own on/off switch, so it can sit in the chain as a set-and-forget curve you kick in only when needed¹².

The five EQ bands and their center frequencies:

Each band offers +/- 12dB of cut or boost², a range Bass Musician Magazine's reviewer Jake Wolf confirmed in his 2022 review of the pedal line⁴. A separate EQ Output Level control gives +/- 9dB of overall level trim, so you can compensate for the volume change a big EQ move causes².

Because the two networks switch separately, a player can leave the filters always on to clean up the signal feeding the rest of the board, and treat the five-band EQ as a second, footswitchable voicing. That is the "dual function" of the name: filtering and equalization as two distinct tools rather than one combined curve¹².

Headroom depends on the supply voltage. At 9V the maximum input level is +5dBu and the maximum output level is +9dBu; at 18V those figures rise to +10dBu in and +20dBu out². For a bass player running hot active pickups or stacking boosts, the higher voltage buys cleaner headroom before the EQ clips.

Designers and the redux collaboration

The re/Q is the second pedal from what RockBoard's PedalPedia calls the "redux collaboration"¹. That collaboration brought Jeff Genzler and engineer Andy Field back together to develop the company's line of bass and guitar effect pedals². Field is a former Genz Benz engineer; Jeff Genzler founded Genz Benz amplification in 1984⁴.

Genzler Amplification itself was founded later by Jeff and his wife Catherine, along with Scott Andres as principal engineer⁵. Before the pedal line, the company was known for its amplification products: the Bass Array cabinet designs, the Magellan series of bass amplification, Acoustic Array combos, and the Nu Classic series of bass cabinets⁵.

The re/Q is the second pedal from the "redux collaboration" between Jeff Genzler and engineer Andy Field, and the second model in the Genzler Amplification bass pedal line, a companion to the 4 ON THE FLOOR Classic Overdrive³.

Power and connections

The re/Q accepts power supplies from 9VDC to 18VDC of the low-noise type, in either polarity, with the pedal auto-detecting the plug's polarity, and draws a maximum of 40mA². No power supply is included in the box².
