Magnatone Amplifier

Magnatone amplifiers are vintage American tube amps renowned for their pitch-shifting vibrato circuit, which produces a true pitch modulation rather than the tremolo effect found in most guitar amps. Billy Gibbons became a prominent advocate for Magnatone amps, using them to achieve the lush, swirling modulation and warm clean tones that complement his gritty Les Paul crunch. The Magnatone's unique vibrato creates a shimmering, three-dimensional quality that adds depth and movement to sustained chords and melodic passages. Gibbons's use of vintage Magnatones alongside modern reissues has helped revive interest in these once-forgotten amplifiers.
