I'm playing a strat through a Jim Dunlop Fuzz Face (Band of Gypsys edition) into a Marshall DSL5C combo. I'm looking for a starting point for getting a Hendrix-y tone. Can anyone recommend some settings, or advise where to start? Playing the fuzz face into the clean channel doesn't give much sustain, yet fuzz face doesn't have too much impact using the Ultra Gain channel on the DSL.
Try out all the positions on the pickup selector of that strat. Turn up your amp loud. Stand close to it. You're never going to sound quite like Hendrix, so just make sure that the amp is set such as to produce a balanced sound with various distortion levels available through the dynamics of your playing.
If you were to stack the fuzz face with the distortion channel, set the gain fairly low on both, unless you want it really out of control. Turning up the volume on the fuzz face also helps to saturate the preamp and recreate the sound of an amp melting down.
try old marshall distortion pedals, wah-wah like Hendrix used or hire an engineer tomake set of effects for you as Hendrix did. However I am sure that his music sound good if performed well on modern intstruments. Jimmy was a left handed player and it is not easy to copy what he was doing with his guitar, and there is no need to copy anyone exactly, I guess.https://www.groundguitar.com/jimi-hendrix-gear/
