Has foot switch, reverb works very well (lots of reverb), tremolo not working very well, you can tell it's trying but the effect is not very pronounced. Non-original concentric knobs and speakers and rear panel. The newer speakers Jensen Alnico P10R's. These speakers must be slightly higher power than the originals, because the footswitch won't fit into the metal footswitch holder because it hits the speaker basket before fitting down into the holder. 3-prong power cord is probably not original. This covering is usually referred to as 'tree bark'.  All inputs work, 30W combined output when switched to mono mode. Stereo all the way inputs to output. Sounds great
