Best small acoustic guitar amp I've owned. The frequency response sounds wonderful and I don't need an external EQ like I do on most other acoustic guitar amps. I use it with a classical guitar fitted with piezo disc pickups on the underside. These produce 8-10 volts which overloads many guitar amps, but this amp has a pad that levels it perfectly. The built-in DI is a great match for larger venues where I can use this amp as a stage monitor. Amazing volume from such a small amp. I haven't found any down-sides to report. Happy camper.
