For sale here is a used Mesa Engineering Subway+ Bass Preamp/DI, in excellent condition. This is easily one of the best bass preamps I have ever used, like having a fully featured amplifier without the power section. 4 band EQ (with sweepable mid bands), Deep and Bright switches for extra low and high end, a voicing knob for a flavorful mid scoop, a high pass filter for tightening up low end boom, a boost switch (with adjustable level knob), a mute switch, and all the inputs and outputs you could want in a pedal. Sounds and looks absolutely pristine. Only selling it because I'm moving to a digital rig for convenience.
