From the vendor

Another lovely wobble box, this time getting somewhere close to the throbbing goodness found on a vintage Vox amp.

Simple build using using modern, more available parts than the vintage original, but sounding exactly the same. Pot values and tapers have been fiddled with for a much better range and sweep too.

Supposedly the favoured trem of Phil Manzanera, and used by Mr Bonnamassa (apparently), so what's not to love?

Board-mounted pots for minimal wiring and easy enclosure mounting.

If you want the PCB without parts there's a link for that at the bottom of the page.

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.

Enclosure (pre-drilled) is available as an option with full kits, and can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included.

Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.

Inspired by: Colorsound Tremelo

Difficulty: Easy

PCB size: 50 x 22mm
