Vox™ Treble Boosters

This is a replica of the Vox Treble Booster. This booster was originally installed in guitars or in a small unit that plugs into the guitar.  It uses a silicon transistor and comes in a couple different configurations.  The original didn’t have a volume control, but there has been a schematic on the net for a long time that includes a volume control, so we’ve included that modification here as well.


Here’s the modification to include a Volume control. The Bill of Materials file above includes the part values for this modification.


Here’s the modification that has an input capacitor switch and also includes a Volume control.


Buy a Vox Treble Booster Complete Kit. Includes all the parts and materials you need to build one, all for about the price you would pay for a PCB and parts.
