The British Pedal Company Dallas Rangemaster from the Vintage Series is an authentic reproduction of the legendary Dallas Rangemaster treble booster, one of the most celebrated effects in music history. First introduced in 1965, it has been favored by renowned musicians such as Eric Clapton, Tony Iommi, Rory Gallagher, Brian May, Marc Bolan, and Ritchie Blackmore, among others. The original purpose of the Dallas Rangemaster was to amplify the guitar's signal before it reaches the amplifier, enhancing the higher frequencies in the sound. During the mid-1960s, the demand for a treble booster grew as British tube amplifiers often produced a somewhat dark and muddy tone when overdriven, especially with humbucking pickups. While it is primarily labeled a treble booster, the vintage components within the Rangemaster’s circuitry can introduce distinctive distortion and overtones, resulting in a more focused yet distorted tone when paired with classic British amplifiers.
