For a few years, I used a Roland Bass Cube60 (the old orangey coloured ones) with my Sessionette75 on top on clean, with the bass rolled off a bit, fed from the Cube's line-out. The whole thing didn't have massive bass obv, but a fantastic snap for punk-funk (think RHCP before they were around). The top end made it cut through enough to gig. Never damaged the guitar amp, still using it!
