JollyRanger

JollyRanger is a Treble Booster-type circuit (aka: Treble Ranger), built on a Poteniometer sized circuit board. (product photo is of a previous version)

It features the ability to choose either a thru-hole NPN Germanium or silicone Transistor or a Surface-mount NPN silicone Transistor (such as the MMBT3904 or MMBT2222).

I recommend installing Polystyrene Capacitors in C1 and C3 for extra treble mojo-tone, although you can use your own thru-hole capacitor of choice.

Add to an existing circuit as a pre-amp or use in a tiny stompbox enclosure as a stand-alone project.

Verified.
