I wanted to try that classic JTM sound with KT66 tubes and ask my amp guy to do the mod cause my amp didn't support KT66 tubes. I'm glad i did because it sounds so nice! I also notice that, fuzz also works better with KT66 for some reason? At least with JTM45. Definitely not going back to EL34 anymore with this amp.
I use my Harley Benton attenuator to get louder levels, and focusrite scarlett sound card to capture guitar sound. Mic is Behringer SL75C. Guitar is my strat with Fender 69 custom pickups.
