When I hear players express confusion or frustration about compressor pedals, it tends to be less about a sacrifice of dynamics (the devil’s bargain in any compressor) than a lack of control and perceptible benefit. But with its 6-band EQ, wet/dry mix control, relative transparency at flat levels, and relative quietness, J. Rockett’s I.Q. compressor has the ability to be super subtle or powerfully transformative. You’ll rarely find a compressor that can so drastically alter the timbre of your instrument or lend so much creative control of the compression effect.
The heart of the J. Rockett’s flexibility is the six sliding boost/cut frequency controls. Each is illuminated when the effect is on. The six frequencies under your control are 100 Hz, 200 Hz, 400 Hz, 800 Hz, 1.5 kHz, and 3.2 kHz, and each slider gives you 18 dB of boost or cut to work with. As you can imagine, the EQ and boost profiles you can create within that scheme can be pretty radical or specific depending on your need.
The EQ section is situated before the compressor in the circuit. But the simplicity of the compressor section itself means you’ll need to use the EQ to do the lion’s share of the tone shaping. There are no controls for attack or release, and like the Ross and DynaComp, it uses a two-knob control scheme to control overall output and the wet/dry mix. That means the compression ratio and, to some extent, the attack and release are fixed. But just as on the Ross and MXR units, those limitations leave a lot of room for tone sculpting. And as it turns out, they are well tuned for the dynamic nature of the EQ section.
