The Acoustic BPDI Bass preamp + DI pedal brings the classic bass tones of Acoustic to a convenient preamp/D.I. box format, ideal for bass players looking to expand their tonal options in any performance situation. Tone shaping is achieved with a 4-band EQ that includes Low, Low-Mid, High-Mid and High bands, allowing for precise control of your signature sound.

Switchable Acousti-Comp Compression circuitry tailored for bass guitar helps to control playing dynamics while the Frequency Notch knob and Shape Switch Controls allow you to quickly find your desired tones. Convenient dual footswitch operation allows you to bypass the pedal and control Overdrive on/off operation, while the Overdrive Level and Blend sets the exact degree of the effect to your clean signal. In addition, the overdrive can be used when the BPDI preamp section is bypassed, allowing for use as a standalone OD Pedal.

Exhaustive input/output options make the Acoustic Bass Preamp + DI pedal an indispensable tool on stage and in the studio, with XLR or 1/4” balanced output, 1/4" Thru Output and an FX Loop that can be turned on or off with an optional footswitch. In addition, controls like Input Gain, Master Volume, switchable Active/Passive input pad and Ground Lift Switch combine with 1/8” headphone out and AUX Ins for a full-featured performance and practice solution.
