I'm looking for a real vintage Big Muff pedal, particularly the third version (mid 70s - early 80s) with the tone bypass switch etc...
I found one for about $175 AUD but it's very scratched up and looks like it's seen a hell of a lot of use.. but apparently it works fine.
I used my friends 70s Big Muff with the tone bypass switch recently at a recording session and it was brilliant! I loved it at first play... and I asked him how much he got it for and he said he paid about $150 on ebay for it.

I'm pretty sure it's the third version that I'm after... so I was wondering how much these 70s Muffs go for and are worth?
