4-5 star rating here are mostly marked by beginners who haven't listed to the decent amp. So lets start, sound is good if you are going to use clean channel, overdrive/reverb quality are quite low, you still could get decent sound by running all through processor/pedals to get that nice sound. The volume is actually good, more than enough to go along with a drummer and make small/average gigs. Features are not that much, EQ,reverb,overdrive channel.. which is the basic plus this all doesn't have best quality. Can't say much about quality as i got it only yesterday. This is good average amp, so im giving it overall 3 stars which is not bad, considering that 5 stars should be given only in exceptional cases to outstanding products.
