The One Control Granith Grey Booster features a high-quality boost of up to +15 dB with minimized switching noise due to BJF engineered circuitry. This booster is able to attain the equivalent S/N ratio of a high-end amplifier. In order for this to happen, the circuitry was created to fit the frequency range of an electric guitar, which lowers some overtones that could otherwise be present with other boosters. The frequency characteristic of the Granith Grey Booster is unique - if you turn up the output without changing the frequency characteristic of incoming signals, you won’t be able to ignore the unnatural 'feeling' it creates. This discomfort is caused due to the difference between the frequency characteristic at the original output level and the actual output level. The Granith Grey Booster creates the necessary frequency characteristics while the signal passes through the circuit. By doing so, the Granith Grey Booster realizes a pure and high quality boost sound without compressing the sound or narrowing the dynamic range. You can use it by directly connecting any guitars and basses. From single coils to humbuckers or from active to passive, The Granith Grey Booster does it all.
