This is more of a discussion than advice if anyone wants to partake, but advice is good. Never a master always a student
I have about 8 hours on the unit (I should be learning material for tomorrow, but I'm digging into the KPA). I've built a beautiful clean rig which I like using the AC 30 through the FB Man Cab (Fender Bassman 1959 with 4 10" Jensen Alnico P10Q speakers). Sounds musical with my DBL Fat Strat.
Now I'm building a hi gain rig using the EVH 5150 iii Red Channel through Hesu 4x 12. It's a Lars Luttege rig. Sounds great. I'm working with Pure Cabinet, Hi and Low shift modes in the Cab section. Dialing what sounds like a true cabinet to my ears. Alos dialing in Shaping and Bias and Ect. looking for that response I like. That's the toughest part in the new endeavour. Searching for the response one would feel playing through an "analog" amp.
Wrote a tune while doing it too. Good stuff.
