Ps, I don't tune way low. Usually standard C with 60s. I use good pickups etc. Been a tone snob for 10 years or so now lol so tons of high gain heads have been through here. Lots of tube/speaker swapping has went on with almost every head I've had. I have 5 4x12 cabs loaded. Pickups are usually black winter, mojotone sledgehammer, duncan sh6, manlius vintage modern, and I've had 2 BKP offerings, miracle man, ceramic warpig. Kept the warpig. All in mahogany guitars. So things are usually consistent with how I'm running the tones. This is one of the more unique voiced amps with a super vocal midrange, alot of thickness. The closest to it tone would be an archon 100, the archon has less congestion and in my opinion more focused mids. I just retubed it again last night, put 4 Tad 6l6 back in at 29ma, and 2 mesa El34 at 31ma. Something about the kt77 in my opinion further congested the mids.
