This combo has a 12" speaker. Its rated at 100 watts RMS. It is a very decent small gig/practice/rehearsal amp. I used it for several years as my primary amp for my "upright" gigs along with low volume electric gigs. It works great. The amp has some "trunk" rash on its tolex covering, though it is NOT scrapped through to the wood anywhere. One of the metal corner protectors is missing. For the $130, I will apply $15 toward shipping the amp.
