Custom hand made all tube high gain amp built into an ENGL Screamer amp shell. The transformers are also kept. 5 stage tight high gain channel with a adjustable low gain low-end blend in. The signal is split after the first gain stage, runs through an additional gain stage and merges back after the fourth gain stage. The unbypassed cathode fifth gain stage blends the 2 signals together with small additional gain. 3 12ax7 so far. One more for the effects loop and another for the phase inverter. So 5 preamp tubes. The power section has 2 6l6 tubes.
