Update:
I'm looking at doing another full pedal build this fortnight, and thought I would do a write-up for it just in case any one else is interested in building one, this time it's going to be an EH Big Muff pedal, these EH Big Muff pedals are a very high-gain distortion pedal, noteworthy for the very fat Fuzz/Distortion tone they generate, supposedly it's one of the pedals used by The Smashing Pumpkins on their 90's albums, also, supposedly Jimi Hendrix used one when he was known as Jimmy James, I'm going to be buying all the needed parts tomorrow from my local Jaycar Electronics store, stay tuned for further updates.
