been using this method for over 20 years. Best results have been with the most powerful tube amps with alot of clean headroom, and flat tone stack are the tickets. Reason why i have 2 majors and my 3 400 watts hiwatts, and a few other heavy hitters, they just kill as clean power amp setups, of course running into external mixes to balance everything is also the key. Full sound spectrum coverage all over the stage- 3 d sound if u will ! Trade off alot of gear to cart if only doing small gigs. But on large stages, this killed. The good old touring days, had alot of guitar techs quit on me, heheheh. But man you want to talk about a wall of sound. If i ever tour again on large stages, this would be the set up i would use. Remember using this new preamp going into the dr405's in stereo, everyone shit, i was bombarded by all the techies, guitar players, engineers, wanting to know how i was getting that tone. I hide the weapons behind a dummy blank front and rear panel in the rack, so one no would find out my secret. lots of outboard gear but that was just for show to fool all these hounds off my tracks, HEHEHE , just the big iron was and limiters/compressors, effects units were exposed and no one could believe what they were hearing, everyone wanted to know who did the mods,, hehehe no mods done to these bad boys but it was the pre's giving me the sound/tones.
the things we do for sound.
keep shredding !
