Nice Les! I run my dirts different than you. I use a clean Fender Blackface/Silverface amp with high headroom and use the pedals for the entire gain sound. I stack a lot and I try to pull a Marshall sound out of it sometimes. All that said, I still think the Pettyjohn stuff would work for me. I'm particularly interested in the Gold - which is their Marshall in a box pedal. I'm always looking for the perfect pedal in that genre to turn a mid scooped crystal clean Fender into a raging mid heavy Plexi. I also think I'd like their Lift pedal, for a nice boost. I'm using the Jackson Audio Prism for that now, and I love that pedal so it would take a lot to move it off now.
