HF Modulator

Peculiar little box from Jen, also produced by Gretsch as the 'Playboy'. So what's it do? Kind of a pseudo ring modulator, though not really. Hey - we didn't invent it!

Basically it's a very fast trem that'll give you a ring-mod type effect if you play the right notes with the controls set in the right place. Useful for making your notes wobbly. Not incredibly musical, but it can sound good if you get creative.

This kit has been designed with currently available transistors rather than the obsolete parts used in the originals. Same sound with less headache.

Three controls: Speed, Intensity, Tone.

If you opt for vertical-mount pots they have round shafts, so you'll need knobs that fix with a set screw. Feel free to wire in 'normal' pots if you prefer a splined shaft.

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 only available with full kits, and will take a battery. Knobs are not included.

Difficulty: Easy

PCB size: 50 x 29mm

Knobs required: 3

Enclosure: 1590B
