The Dallas Rangemaster Treble Booster had a huge impact on the tones of Brian May, Tony Iommi, Billy Gibbons, Marc Bolan and Rory Gallagher and many others. Today we're playing a 1966 Rangemaster through a 1960 Fender Tweed Deluxe. Although the pedal his super simple it packs that classic tone that you can't get anywhere else.
