Ok, so I want to get a Roland KC-550. I want to use it for my Godin Multiac, GR-55, Electric Bass, Godin A4 bass, V-Drum, and my electric guitars using a Firehawk Effects pedal. I'd also use this with my Wind Controller. Will this amp do all what I'm asking it do? I was originally looking at the AC-90 for acoustic work, but for $50 less I can get a much bigger amp. What does everyone think?
