I was looking for info on John Frusciante's rig when i came across these pics (also attached below):
Close ups of the three amps that john uses on stage
The trebles on each of these amps are set so low, but when he plays he has a bright and trebly tone. How does he do it if he sets his amps like this?
Fender American Stratocaster
