HF Modulator

From the vendor

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. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. 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.
