Fair enough he mods them. I'm just saying modding PCB's is harder than modding eyelets or turrets. Nothing wrong with using PCB's. It's a testament to say he can works on Bogners and such. The Uberschall I had looked like a nightmare to get into. Doing intensive mods on PCB amps must be hard work. Especially is its things like the Bogners or Dual Rec's, or stuff using double sided PCB's and so on.
I haven't really into the Fortin stuff much. I like the idea of the Bones, being a single channel amp with a lot of options for added stuff, and his mods sound good, but thats all. I didn't know his gain circuit was vastly different to any other common ones. Is there a place where the Fortin stuff is discussed more?
