Unbelievably good tube pre-amp pedal, hand built by the Electron Brothers up in Brisbane.

This pedal runs two 12ax7 tubes at the same voltage as an amplifier, making this a proper preamp-in-a-pedal.

Based on the 'British' amps from the late 60s to early 80s, this pedal is basically the preamp of a modded JCM800 (and is probably better than most of them out there).

It's got the normal gain, vol, and TMB tone stack, but then also gives you three toggles, Fat, Response and Bright allowing you to further shape your sound.

Honestly, this pedal is just really fucking good. Watch the demos, because I can't describe it properly.

Selling to fund amp repairs :(
