I need something to get a similar effect as Mark did on the run out to "Speedway at Nazareth" where he simulates colliding cars (with doublestops, I assume) - a nice break up. Someone recommended the Keeley "Fuzz Head" - I hate pedals and rarely use them! Comments welcome if you know what I'm talking about on the recording. Yeah, I know he uses Komets now. This recording is a few years old. Thanks, Pete.
