My poor V4 blew a fuse the other day, second song into our gig. I ended up borrowing another band's bass head to finish - a GK800RB. This thing blew the V4 so far out of the water volume and bass-wise i'm wondering what the hell happened! Now, the tone sucked (IMO - remember, the V4's where it's at tone-wise for me), but the power was quite impressive. Which makes me think I need new tubes for the V4 or something! It just didn't seem right... Has anyone else ever had this happen to them? - your pride and joy being p!$$ed on by something you normally p!$$ on yourself?
