I was after the Neil Young Rust era sounds for a log time. I know where his sound comes from, based on the article in the Tone Quest Report September 2007 (the interview with Larry Cragg). I spare you you the recapitulation ... it has been discussed a lot of times. I own the Durham Crazy Horse and I have to admit that I love this pedal and its sound but, something was amiss. But this pedal gave me the right idea. It is basically a distortion unit feeding a fuzz. Today I have found the right (IMHO) combination of devices. Tonefactor Hellbilly > Earthquaker Hoof > Fender Tweed (clean) instant torn speaker, cooking tubes, exploding amp, Rust era sound. Sorry no clips at the moment ... maybe next week.
