If so, why go looking for something else. I started with a Peavey Bandit 112 years ago. They are a great amp. A real workhorse and dang near indestructable. You're not going to have the effects that you have on the Roland though.

I tried many, many amps when I was looking, but I was looking for a loud, full on rock gigging combo. The Peavey 5150 combo was what I ended up with. I know, I know, it's the Van Halen model..but that seriously made no difference to me. I took my guitar and my brother (who was our drummer), played through every combo I could find that was less than $1K, and picked the one that sounded the best. But...this is not an amp I can sit around the house playing as it just has too much volume at the lowest settings!!

My personal liking is my Strat through my old Fender vibrochamp and my LP through my Peavey. The Strat sounds like junk through the Peavey to me.

It really comes down to what you like. If your cube sounds like a Fender on one setting and a Marshall on another I'd say you have the best of both worlds. Quit looking and practice, practice, practice.
