Hi well i tried the unibass last night at loud volume with the band and its going back for a refund. Here are my findings: At lower volumes into amp ( with effect distortion ) it sounded good. With band it sounded either lost or if turned up my bass sound suffered. Tried the effect out into a di box and then PA and this sounded poor, the distortion was kinda weird sounding. I conclude that to make this work well you need to connect the effect output to a guitar amp and then it would work well. For me that would mean too much gear and hassle so its a great product just not for me . I am awaiting the arrival of the MXR-M80 and i will try that out. My aim well its too fatten my sound, give it a lift etc etc during songs when the guitarist is playing a solo. I like the fact that the MXR has a few more features over the SABDDI as i do not need Tube emulation just a bit more lift and full grunt now and then. Hope this helps people looking to do the same.
