Lovepedal Eternity
Lovepedal’s bufferless Tubescreamer with asymmetrical clipping. Actually I think that makes it a bufferless Boss SD1
Kay T1 Tremolo
You may struggle to get hold of the 2SC828 transistors, so just try any high gain NPN silicon. Just make sure the pinouts match, or use some small heatshrink tubing or offcuts of wire insulation and twist the legs if you need to. Geiri’s demo:
Lovepedal Kalamazoo
