1 GuitarFarm 2 years ago Decided I needed an amp in between a Champ and all the large 6L6-based amps I've been building. Settled on the 5C3 circuit. I really like it. Just waiting for the 12" Tone Tubby to get broken in. This circuit seems very warm at low volumes and breaks up early into nice ZZ Top tones at half volume. Haven't really pushed it yet. Hope you all like the pictures.
