Magic Vibes Tremolo

From the vendor

You can never have enough wobble on the board, so here's a nice optical trem to add to the arsenal, updated for your pleasure in 2024.

Supposedly very similar to the trem on a Magnatone amp (there isn't one at FuzzDog HQ to verify that - sorry!). What we do know is this gives a pleasing throb which ranges nicely from subtle to wob-wob, but doesn't get into choppy territory.

After much experimentation with different vactrols and LDR - LED 'roll your own' combinations, this kit works a treat with a high-intensity red LED and a LDR with very high 'dark' resistance. Would you expect anything less?

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. Please choose appropriate knobs.
