E-H Little Big Muff Pi First Look Here's a closeup look at the new EH Little Big Muff Pi next to one of my custom pedals in a Hammond 1590BB enclosure for size comparison. This is a gut-shot of the Little Big Muff showing the working parts... almost all surface-mount components so it will be difficult to mod. Obviously it is true-bypass and there is a separate pcb soldered on the footswitch lugs to simplify the wiring. It's a very well engineered box! How does it sound? It sounds like a Big Muff, what else? The transistors are marked MMBT5962, which is a low noise, high gain general purpose device in a SOT-23 package. HFE is 450 and up! The schematic should be easy to draw since the component values are marked on the pcb.
