The first 40% of the depth was imo unusable, making the circuit sound like stock 66 tonebender - thin and piercing. Which is without a doubt a feature in the original. But i wanted a bit more balls to it. So i ended upping the 1n for 6n8 and lowering the depth pot for 250K. Didn't do anything else, but i think that upping the right hand side 47n for 100n could be worth a try too.<br /><br />Put 2N2369 for Q1 and 2N2222 for Q2.

Quite similar to the DAM Drag'N'Fly I built earlier, but with a touch less gain, and a bit more clarity, even though there seems to be a bigger bass presence in some way.

I followed this exactly, have checked and re-checked but cannot get it working. Have looked at your version which differs in quite alot of ways, more components, layout etc. I see your version has been verified, and would like to try it. I was wondering if someone could help me with the wiring to the footswitch and pots, a diagram would be great, or just advice, really appreciate it, love this site! Ta from England!
