ive got 4 Phillips ecg STR-387's in the power section which sound incredible. GE 12ax7 in the preamp, ge 12at7 for the reverb and a ge 5751 for the phase inverter. the 5751 in the phase inverter sound really smooth and allows me to get more gain while keeping the really good cleans. ive got it on top of a 2x15 cab with 2 jbl e130's. Im going to post some videos on youtube this week because the way mine is setup, It nails SRV clean tones from post "Texas Flood" era. with the deep switch engaged the bass sounds incredible through the two 15's.
