Gearank Recommendation

The Acoustimax appeared on our recommended list for Acoustic Preamps when we published the first edition in May 2016 and it remained there until December 2018 when it was out-ranked by other preamps.


BBE Sound Inc. is known for their popular “Sonic Maximizer”, which improved the clarity and volume of many recordings. They have since branched into live sound reinforcement and have made their technology suitable for acoustic instruments, resulting in the BBE Acoustimax.

While it may not have as many extra features as other acoustic preamps, it works great where it matters, having extensive tone shaping controls and providing great sound courtesy of the built-in Sonic Maximizer.

This may not be a do-it-all type of acoustic pedal, but it definitely fits the preamp bill.
