Retro-Electro Silicon Treble Booster


Retro-Electro Effects about the Silicon Treble and Mid-Range Booster

Silicon transistor treble booster circuit based on the old JHS, Hornby Skewes model reputedly used by Ritchie Blackmore and Rory Gallagher. Modified by converting to NPN and the usage of a BC108 transistor for more gain and bite. Also has the addition of a mid range boost selectable by a slide switch on the face. Also volume control, true bypass and LED indicator. Power by 9 volt battery or power supply.
