The Dallas Rangemaster was a germanium transistor-powered guitar effect made in the mid-1960s which was relied upon heavily by Brian May, Tony lommi, Rory Gallagher, and many others to achieve their signature sounds. It was marketed as a “Treble Booster,” when it actually boosted the midrange and treble frequencies, at the same time imparting an incredible harmonic-laden distortion while also driving the tube amplifier to distort more.

The Fulltone CS-Ranger brings this back to life, with 5 extra frequency ranges, true-bypass and top-shelf components.
Premium american quality from the Fulltone custom shop at it’s best, using traditional full-size components.
