It says 40 watts on the back of the box, but 15 on the magnet I think... but it's a RG10 so I would assume that means a 10 watt amp. It has tiny lil balls, and at high volumes is very distorted. It's 10 yrs old. Volume, Overdrive, Trebble, Bass knobs on it. One input, one output. It's a tube amp. That's all I really know.
