ever have a gig as an opening act and have to use the back gear ? drums and bass rig are the back gear and sometimes you get to play on some cool setups and sometimes you dont, what is the best and worse rig you ever had to play on? the best for me was a killer rig with 4-eden d 4-10 XLT cabs and two gallien-krueger heads, the sound was great! the worse was an old fender bassman that had a short and it made me see stars !! i can still feel it! any good storys on this????
