Bought this while I was playing in a house-bandish outift with cover songs ranging from R&B, funk, rock, pop. It handled it all really damn well from a clicky slap-bass sound to thick tubes to nice overdrive.
Later after that project I really had no use for it since I switched over to mostly rock outfits and produced my overdrive from the amp. However, this thing saved our band in the studio. Our engineer only had passive DI-boxes with him, and we encountered massive hum and hiss issues with them. No problem for the Bass Driver; I dialed in a dry sound, used the battery as the power source and we hooked the thing to our engineer's gear; zero hiss nor hum.
Never letting this box go.
