I got to try a bassbreaker 15 for the first time yesterday, and I admit I was blown away. Awesome, awesome amp. The only thing I can compare it to is the BJ Nos tweed that I play on occassion whenever hte local stores have them. every time I play one of those, I leave saying, "someday I'll own one." I wish I could play them side by side, but that just doens't happen out here. Has anybody been able to play them both and compare them?
