Base pedal: Dallas Rangemaster
The Dallas Rangemaster is one of the most consequential treble boosters in rock history — the circuit behind Tony Iommi's crushing riffs and Brian May's violin-like tone. This germanium-driven boost stacks beautifully into a cranked amp, thickening the mids and adding a distinctly vintage, slightly compressed snarl.
