Vox Treble Boost

Vintage treble boost. Need we say more?

OK, a little more. Originally a plug and play unit with no control, our PCB adds an optional volume control, though the signal sits just above unity if you build it without.

Extra spots on the board so you can use the original 2N2924 transistor (supplied with the kit) or more common CBE pinout cans such as 2N3904 etc.

We also include a few extra input caps. The original 500pf cap cuts out a great deal of the signal. We recommend going a little higher, so supply 820pf, 1n and 2n2.

Board-mounted pot (if you opt for it) for minimal wiring and easy mounting in the enclosure. If you don't want a pot the circuit can be firmly fixed to a Direct Connect daughterboard for mounting.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.
