Combining a pristine bass preamp with a studio-quality Direct Out in a Phase 90 sized box, the MXR Bass Preamp features separate input and output controls and a 3 band EQ section with sweepable mids from 250Hz to 1khz. It’s all delivered super clean with high head room thanks to Constant Headroom Technology; use the pre/post EQ switch to set whether or not the Direct Out signal is affected by the EQ section. The ground lift switch removes ground loop hum.

• Switchable buffered Direct Out or true hardwire bypass.

• Powered by 9 Volt battery or AC Adaptor (not included).
