Roxi starts with a precision rotary switch gain control, which levels up the audio performance, especially in higher gain ranges (ribbon mics welcome). A 2 position high pass filter gives excellent control of problem bass / rumble areas at 75Hz or 150Hz. A 3-band EQ with sweepable mids rounds out the tone shaping. The FX loop can be defeated by a footswitch and has an onboard blend control to run your effects at 100% and adjust wet / dry amount on the preamp. The input is a combi XLR / 1/4″ jack, so it can run as an instrument preamp.
