Sold as for parts or not working as I can't fully test all its functions. However, the amp does power up and makes a whirring sound - presumably an internal fan. I have had a little tweek with the knows and buttons and I didn't notice one of the lights didn't light up when I pressed the adjacent button - see picture with my finger in! Condition otherwise is as seen. It was used by a Merseyside musician gigging on a fairly regular basis, hence the wear and tear.
