This is designed for acoustic guitar, but I purchased it to use on acoustic bass for DI tracks. It was definitely helpful and brought out more of the acoustic vibe. I’ve heard some sampling pedals that do even better job, so I know there is room for improvement, but this did help quite a bit. Not exactly equal to the microphone, but enough that when I needed to duck the microphone out because of noise or other issues, it was definitely much better sounding than the DI even with EQ. Still have to try it on acoustic guitar at some point, but worth the purchase price – at least the on sale purchase price. The full retail price is pretty expensive. Hoping that if there is an update, there might be some focus on acoustic bass presets, though I know that market is pretty small.
