Why these settings

Carpenter uses far less gain than expected for modern metal — the tightness comes from picking precision, not saturation. The Catalyst's Origin High Gain model approximates the JMP-1's Marshall voicing. Mid boost at 7 is critical: the original recording relies on mids to cut through despite the extreme low tuning. Your GRG170DX's INF humbuckers are hotter than Carpenter's active Fishman Fluence pickups, so gain stays conservative at 6 to preserve note definition.

PRO TIPCarpenter uses an octaver pedal for much of Ohms' low-end rumble rather than relying solely on the 9-string's lowest strings — if your riffs feel thin in standard tuning, a pitch-shift or octave effect underneath would get you closer than downtuning alone.
