Aggressive mid-forward crunch with snarling bite, tight low end, and raw harmonic saturation

RECOMMENDED — not currently owned. Slash used a Boss GE-7 to push mids and tighten the amp. A TS-style pedal achieves the same effect: low drive, boosted level, slight mid hump. This fills the gap your MG's voicing lacks vs a real JCM 800.

Why these settings

Your MG30CFX is darker and more scooped than a JCM 800, so mids are pushed to 8 (vs original 7) to compensate. Your Telecaster's single-coil bridge pickup is brighter and lower output than Slash's Alnico II humbuckers, so treble is dropped to 5 (from 6) and presence to 4 (from 5) to avoid ice-pick highs. Gain stays at 7 to approximate the modded 800's extra saturation.

PRO TIPRoll your Tele's tone knob to 7 to tame the single-coil spike and fatten the attack—this mimics the rounder harmonic content of a humbucker without losing cut. Tune down 1/2 step to Eb standard to match the recording's string tension and note voicings exactly.
