Yes sorry we missed this. I have been tweaking the forum for weeks now trying to get it setup just right as well as keeping spammers at bay.
Anyway I always was a fan of the Mark tone so I find this interesting. I also share Wilkies concern however my guess is that the circuit is producing a starved fuzz tone similar to what Marks early Red Album sound is. So I think mayeb having a 9 volt circuit with a Voltage Sag added to it might be very worth investigating. Best of both world scenario.
Can you post an audio clip of what you currently have?
