my set up is ...
fender strat plus with lace sensors
peavey trans tube
korg 1000 tone works pedal in front of the amp (do not use efx loop)
i use the clean channel only eq flat
master volume on 3
get sustain every time with my distortion setting on the korg
actually i have had quite a few positive comments on my sound in view of the fact that the gear in many respects is cheap stuff but i think all tube would be better but i dont want to lose the usable feedback
