Rangemaster

Dallas Rangemaster with selectable treble or mid boost.

This is a replica of the Rangemaster treble booster, the classic effect used most notably by Brian May, Tony Iommi, and Rory Gallagher. Germanium transistors boost treble into sweet overdrive, while the bass stays clean.

This version has a switch that adds a second capacitor to boost the mids. Like the original, this effect uses a positive ground running on 9v battery power only, as the positive ground doesn't play well with power supplies.
