35 watts!! 10" speaker!! Sounds great with built in effects, delay, chorus, vibrato,  flanger, tremolo, overdrive, and reverb. this also doubles as a rack effects unit, it has a line out so you can run into your 2x12 amp or stack and it functions just like a multi effects rack, this works well as I tried it into my marshall stack and it is awesome!!  the owners manual talks all about it so the line out is meant for that, and a 1/4" jack instrument cable is all it takes, just like an effects pedal. also has built in tuner, so you can practice at low volumes with great tone, then you can run the line out into your recording console, mixing board, or another amplifier and use it as the best multiple effects rack you ever heard!! make no mistake, this amp is awesome all by itself!! and you could mic this amp on stage and play anything from johnny cash to slayer!! This amp is also good for vocals!! Yes you can sing through this amp w/reverb and delay etc etc!!  so for you singers out there, this can be used as a vocal effects unit and sound awesome!! $189 for this amp w/free shipping is the best deal on ebay right now!!!! happy holidays!!
