The concept for this amp is the brainchild of ScottVA over on the Weber amps forum. Its basically the initial preamp from an 18W lite, the tone stack from a 5E3 deluxe, a long-tailed-pair phase inverter, and a cathode biased power section. This one is dual KT-66s and it is a monster sounding amp clocking in somewhere under 30W. 

The idea is to keep things minimal, so the preamp is sparse, as is the iron, and it keeps the whole things pretty light. The sound out of it is amazing. Its not too gainy and has a lot of clean head room with a tele and a little bit less with a les paul.  No matter what youre playing it gets a good bit of crunch at the end of the volume dial. The cleans are VERY blackface bassman to me and that is so kickass. The crunch is straight plexi, with a bit more bassy full-ness due to the KT-66s.  Call it something between a plexi and a tweed bassman/JTM-45.  Brilliant.

Controls are Volume and Tone because you dont need anything else in life.
