Repeater - updated Vox Repeat Percussion

Instant Spacemen 3! Just add fuzz and wah.

Quirky little box of fun. The original was a box that plugged straight into the guitar jack socket. Sound? A reverse-sawtooth tremolo-type affair. Very choppy.

Stock, it cuts the signal completely between 'beats', giving the percussion effect the name suggests. This version has an optional depth knob to tame that chop and give a wider range of effect. It has also been updated for more output, and has an internal volume trimmer to set it to unity (or over, or under, as you wish).

Also added is a switch to change the speed range available. At higher speeds it sounds almost ring-mod-ish. Also included is an extra input capacitor so you can go with the original thin tone or a normal, full range tone.

Kit comes with a tested 2N2646 (the UJT transistor that does the magic).

The latest version of the PCB has board-mounted pots, optional board-mounted micro-toggle switch (or you can wire a normal switch offboard), and the option to use a cheap, readily available PUT instead of the 2N2646. The PUT option gives the same sounds, but the speed control locks open at the extreme end of the turn, hence we only supply the kit with the stock 2N2646. Due to the nature of the effect you may get some thumping or ticking in your signal. Nature of the beast.

If you go for the micro-switch option the build requires some very neat soldering as the switch mounts over the top of some solder pads. It's easy enough, but not one for a beginner. A standard toggle switch has to mount above the pots as shown in the images.

Boioioing! 5 product stars
"This was my second kit from Fuzzdog, and I have bought more since. His circuit boards are beautiful. The instructions are easy to understand and the results are consistently excellent. This effect is good fun, and I've written a couple of very spaced out tunes around it. Like he says, fuzz and wah go very well with this. I've got another kit on the way (sunny t distortion)! Brilliant kits and brilliant customer service. Thanks mate!" Mick Jones - 12/08/2016

"A very nice kit: easy to built, with high standard grade components and parts.KILLER SOUND! Love it! EXACTLY what i expected: very percussive, hardly sliced and plain sound, with any loss of volume" jerome - 03/12/2015
Spacemen 3 in a box 5 product stars
"Description says that 2 knobs are required, but I managed to assemble it all by myself (sorry, couldn't resist). Easy to build even for a beginner, couple of questions answered very promptly by Poodle. Sounds great. Buy it." Pete - 28/03/2014
Just like the original, only better. 5 product stars
"Easy build, good instructions and quality components. The sound is amazing. I had a Vox Starstream XII guitar with the onboard Repeat Percussion. Poodles box nails the effect, only better. No volume loss, no tone loss and the internal volume trimpot let you set the effect to volume unity or boost it for added mayhem. Buy this kit and it will take you to the other side ;-)" Tjarand Matre - 19/11/2013
