Can't stop amp settings — Marshall MG30CFX
The Red hot chili peppers guitar tone for “Can't stop”, dialed in for a Marshall MG30CFX with a PRS SE Custom 24. Studio cut, By the Way (2002) - iconic opening percussive funk riff
1960 Fender Custom Telecaster (or '62 Stratocaster) into Marshall Major 200W & Silver Jubilee with Boss CE-1 preamp boost and MXR Micro Amp

The MG30CFX lacks a presence control, so treble is boosted to 7 to recreate the cutting spank of Frusciante's single-coil into a cranked Marshall Major. The Crunch channel at gain 4 delivers Frusciante's edge-of-breakup grit without mushing out under heavy picking. Because your PRS SE Custom 24 has higher-output humbuckers compared to a vintage Tele or Strat, rolling guitar volume down slightly to 9 clears up the bass and prevents excessive preamp saturation. Solo switch: engage the OD-1 channel and push gain to 7 to approximate the Big Muff fuzz.
