Pros
1. Very lightweight. Super portable
2. Good sound quality. The amp just sounds good and reproduces acoustic and electric guitars with great detail.
3. Has 2 combo (xlr or jack) inputs. Versatile for different instrument and microphone configurations.
4. Speaker handles volume without distortion. Even at max. volume settings.
5. Has a tilt back leg for better sound dispersion.
Cons
1. Doesn't have a master volume knob. You can only adjust the channels' volumes individually. This means you're pretty limited in terms of volume if your microphone or instrument has a low output.
2. Very low total maximum volume. Doesn't feel like a 100W amp at all, more like a 50W, although wattage alone really tells you nothing about maximum volume... For reference, if I'm using an electric guitar in a jazz quartet (guitar, bass, saxophone and drums) I need to be turned up to almost max. volume, around 95%. If it's just guitar and saxophone, around 85%. Although I never felt I needed more volume, it's a bit unsettling to be so near the unit's max. volume. The low volumes are felt specially with dynamic microphones, the max. volume is probably not loud enough for a noisy venue (haven't tested it live). Using the EQ's mid band seems to change the volume pretty significantly, so this could be a way to get that extra needed volume...
3. Boomy. Either with acoustic or electric guitar, I have to turn the EQ's low band to 0 to have a usable sound.
All in all, a very good sounding unit that doesn't distort at high volumes, but will probably leave you wanting in terms of volume if you use it in noisy venues.
