The Roland Cube 40GX is a modeling amp, so we harness the onboard Classic Stack voice pushed to gain 7 to emulate the singing saturation of Gilmour's Ram's Head Big Muff without requiring external pedals. The Ibanez GIO GRX40 bridge humbucker has more midrange and output than Gilmour's single-coil DiMarzio FS-1, so backing tone down to 8 rounds off harshness and keeps the sustain violin-smooth. Cube 40GX faceplate lacks a physical presence knob, so upper-harmonic control is dialed directly through Treble at 5. Clean verse: switch amp to JC CLEAN channel with built-in chorus enabled.
