thick sludgy crunch distortion. This shapes how hard the amp is pushed and where the EQ sits for the Graveflower sound.
What makes the Graveflower part tricky
heavy down-picking, doom-y feel & dynamics. GuitarToneAdapt gets the tone right so you can focus on the playing.
Note: Graveflower is heavy and groove-driven — keep the low-mids fat and the gain saturated but not so much that the chug loses definition., Acid Bath are an underground 90s NOLA sludge-metal band, so the gear is only partly documented and these settings are lower-confidence estimates — clearly a STARTING POINT, not a recall sheet. What is known: Sammy Duet played an Ibanez Rocket Roll II with an EMG 81 in the bridge; the amp during the When the Kite String Pops era is reported as either a Marshall JCM900 Dual Reverb 100W or a Randall head (sources conflict), and a Morley wah was used. Mike Sanchez's exact rig is undocumented., The sound is a thick, crunchy, sludgy crunch — high but not super-tight gain, fat low-mids, not scooped. Aim for a saturated JCM900/Randall-style crunch with the EMG 81's tight high-output; dial bass and gain to taste for the doom-y weight., Estimates are community-researched; verify by ear against the recording.
