Ranger Boost
The Dallas Rangemaster Treble Booster is a classic effects pedal introduced in the 1960s, designed to enhance the upper frequencies of electric guitars. Renowned for its germanium transistor circuit, it delivers a bright, cutting tone that helps guitars stand out in a mix, particularly with overdriven amplifiers. Widely used by iconic guitarists such as Eric Clapton, Brian May, and Tony Iommi, the Rangemaster is celebrated for its ability to add clarity, sustain, and harmonic richness, making it a pivotal tool in shaping the sound of British rock and blues.
