The Mustang LT25 lacks physical mid and presence knobs on its faceplate, so mid-forward character is handled by selecting the high-gain 'Metal 2000' or '80s Rock' amp model voice. Adam Jones's Undertow tone relies on a tight, cranked Marshall Super Bass low-end, so bass is pushed to 7 on the 8-inch speaker while treble is kept at 6 to prevent high-end digital fizz with your Schecter humbuckers. Tune your low E string down to D (Drop D) as required for the song.
