I had a roland kc-150 that I sold to get a barbetta. I wish I had held onto it. I loved that little amp, and still miss it. It is lightweight and portable, has nice highs and lows, and if you're looking to sit in with some acoustic instruments, it has more than you'll need. The 12" speaker doesn't have the big thump of a 15", but it does well, and with acoustic it will serve you well.
