Why these settings

The Epiphone Studio 15R lacks Marshall tube saturation, so engage the built-in boost channel with gain pushed to 7 for sustaining leads. Boost the mids to 8 to mimic the Silver Jubilee's thick midrange bark while keeping treble moderate at 5 to tame the 8-inch speaker's natural solid-state fizz. If you add the recommended Marshall-style drive pedal later, switch the amp to Clean and drop its gain to 2.

PRO TIPSlash's signature 'woman tone' lead relies heavily on rolling the neck pickup tone knob down to 3-5 while picking with heavy, aggressive downstrokes near the neck.
