I have nothing but positive words about this amp head. The wattage control knob is perfect for slight tonal differences. If your'e like me and wanted a small, non colored head to run your crazy pedal board though then this little guy is perfect. I very well would have given it 5 stars but mine has had a little of a problem (it happens) while i would be playing at a moderate volume, out of no where the volume would just drop to about half of the level. I had done a little disassembling and had noticed that the wire going to my volume knob had burnt up. It is getting repaired now and hopefully thats all that is wrong with it.
