This amp is perfect in so many ways

This amp is so good... you. can you use at bedroom levels or cranked up plugged straight in and it sounds fantastic. Use it clean or turn up the gain at any volume and it just works. Pedals work great too, sounding like they should. It is difficult to find anything negative with this amp.
