Granger Lead Overdrive 100 valve amplifier

The Granger Lead Overdrive 100 valve amplifier is a two channel, footswitchable scorcher. It is inspired by a legendary circuit that in turn inspired many 90's-era amps (such as the Dual Rec, the 5150 series, etc.) but with most of the popular mods already built in, and completely wired by hand. It's a beast that begs to be tamed. It's also a beauty to behold, with a clear Plexiglas front baffle illuminated by lighting inside the chassis. The normal channel is as clean or as crunchy as you want it. The overdrive channel is fierce, producing heavy overdriven tones sure to please any hard rock or metal player. The preamp section consists of 5 ECC83S valves and power is rectified by robust UF5408 diodes to produce a punchy, tight powerful low end. The power section runs on four 6L6GCs which produces 100 watts. A tube buffered effect loops allows use of additional outboard effects not typically run before the amp input. For the service-minded player, an externally accessible bias adjustment with low voltage test points allows the user to bias the amp when replacing valves without removing the chassis.

A popular option is the 50 watt version. The amp is identical except for the power and output transformers, and two 6L6GCs instead of four.
