2 amps:
1) GK 700RB-II
2) GK MB800
I've been using a 700RB-II as my main amp for 8 years now, but this particular one is the 3rd that I've owned.
I sold the first one when I got a GK Fusion 550, I bought the second one off Craigslist, and the current one was in a 115 combo, but was electronically better (pots hadn't been flushed with DeOxIt) so I swapped it with #2 and sold the combo.
The MB800 was a recent used purchase from Guitar Center that I've played for EVERYTHING since I got it; I wanted to make sure that if it was going to die, it would die during my 45-day return window. But it's solid, light, massively powerful, and sounds great.
I toy around with the idea of getting a second lightweight amp, but I think I've learned that I need to keep the 700RB-II regardless...and I'm not gigging enough to need a 3rd amp.
