01Zoom G1X Four — Treble Booster block (T BOOST or TS BOOST)
Enable T BOOST or RangeMstr model if available; this recreates the Rangemaster pushing the amp into saturation. Place before the amp model in the chain.
02Zoom G1X Four — Cabinet/IR block
Select a 4x12 British cab (G12M/Greenback style) after the amp model for authenticity. Disable any room reverb.
Your Strat's single coils are brighter and lower output than Iommi's P90s, so mid is boosted +2 and treble cut -1 vs the original's cranked-treble Laney settings. The G1X Four's MS1959 (Plexi) model approximates the Laney's mid-forward British grind. The Rangemaster-style boost is critical — it adds the thick, compressed saturation and cuts bass frequencies that define the tone. Reverb stays at 0; the original was bone dry.
