01Behringer UC200 Ultra Chorus / Ultra Metal (or Boss Katana Booster block)
If your 'Ultra' is an overdrive/boost, use it as a tight clean boost in front; otherwise leave bypassed and let the Katana Brown channel handle full gain
The Katana-100 Brown voicing provides the tight, saturated high-gain structure of Mick's Rocktron Piranha and Jim's Mesa rig. Mids are kept at 6 rather than scooped to preserve the articulate low-end attack in Drop B tuning, with bass trimmed to 5 to avoid low-end mud on passive Jackson humbuckers. Clean verse: roll guitar volume down to 3 or switch amp channel to Clean.
