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.Proposed by: Bjorn Juhl.Control: LevelTechnical specifications:• Input impedance: 500K• Output impedance: 2K• Maximum gain: + 15 dB• Supply voltage: 8.8 V ,6 9.6 V• Power consumption: 1 mA• Signal-to-noise ratio: 115 dB• Total harmonic distortion rate: 0.006% (1 kHz)• Dimensions: 39 W x 100 L x 31 H mm (without buttons and switch), 47 W x 100 L x 48 H mm (including buttons and switch)• Weight: approx. 140 g• True-Bypass switch• High quality aluminum cover• Power supply: 9V battery or from a 9V DC adapter not included• Color: Silver.
