One Control Granith Grey

The Granith Gray Booster amplifier enables high-quality amplification of up to + 15 dB with minimized switching noise thanks to circuits developed by BJF. This amplifier is able to achieve an equivalent S / N ratio of high performance amplifier. To do this, the circuits have been designed to suit the frequency range of the electric guitar, which reduces some of the undertones that would otherwise be present with other amplifiers.
