I've been using this amp with my Dupont MD50 and an Ischell CPJ pickup, and have been very happy with it. It delivers clean sound reproduction and good projection at volumes that can easily be heard through a mix that includes another guitar, accordion and mandolin.
In excellent condition, never abused or cranked up to anything like full volume. It's the regular model, with black vinyl covering and Roland carrying case. I haven't included a photo because there are some available on this site in the Amplifiers section, and it's the same unit.
Only selling because I got an AER. The AC60 is a great acoustic amp in its own right, and way cheaper than an AER if you're on a budget.
I'll be at DjangoFest NW this year, arriving Thu afternoon. If you are interested, please PM me and we can meet up there.
