The GRANITH GREY BOOSTER allows a high-quality boost of up to +15dB 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 coud otherwise be present with other boosters.
