Info about the original:
The Sadowsky Outboard Bass Preamp/DI Pedal contains the same famous circuitry built into every Sadowsky bass. Housed in a small footpedal box for use on the floor, it measures just 4.5" x 4.5" x 2.25" and weighs 1.5 pounds. Just plug your bass into the box and then go from the box to your amp, and/or direct to the board.
Controls consist of volume, treble boost and bass boost. The Preamp/DI Pedal is perfect for vintage basses where installation of an onboard preamp would affect the instrument's original condition and resale value. The Preamp/DI pedal is recommended for all passive basses, basses with active pickups, and instruments that have active electronics that can be bypassed. It also works great with all upright bass pickups.
