For gigs I use my existing amp a GK 1001RB II, 700 watts. I've never come close to clipping my amp, and I would say Im in tone nirvana. I have just started using a GK 400RB I bough off DrDave, 240 watts @ 4ohms, I bought this as a backup and to use for rehearsals. Even with this lower power rating I still have plenty in reserve for playing with the band.
