 Satriani has used a wide variety of guitar amps, using Marshall for his main amplifier (notably the limited edition blue coloured 6100 LM model) up until 2001, and his Peavey signature series amps, the Peavey JSX, up until his time with Chickenfoot.The JSX began life as a prototype Peavey XXX and developed into the Joe Satriani signature Peavey model.However he still used distortion pedals with the clean channel rather than the built-in overdrive channels.
