External switch pedal for RC3.

Hey guys, does anyone know how to make a an external switch pedal like the one in the youtube video below? I wanted to order one from this guy but he doesn't ship outside of Europe. I've never made a pedal before but I assume this one would be very basic. Any help would be appreciated!

I'm sold. If we can get a schematic for this little baby, I'm building one, too!! It'll use two momentary (non-latching) switches and a stereo jack. It's got to be incredibly simple inside.

If I think about, it's probably just two simple loops, one to each switch, from the stereo jack (sharing ground lug). You could use two single-pole momentatry switches (http://www.mammothelectronics.com/4SFSSPST-M-p/800-1003.htm), one stereo jack (http://www.mammothelectronics.com/Switchcraft-12b-Stereo-1-4-Open-Jack-p/610-1013.htm), a little enclosure (http://www.mammothelectronics.com/4S1590A-p/500-1005.htm) and about six inches of wire. I'll get the parts next time I place an order and try it out.

Yup. That simple:

Did some searching. There's some talk about the FS6 having one momentary and one latching switch and/or one open and one closed switch. The FS6 can be used with a variety of BOSS products in different ways. It seems from the page above that the RC-3 usage only needs the two momentary switches. It's probably not a replacement for the FS6 in all applications, but for this purpose, it's about ten dollars in parts (or you can make a nice wooden enclosure, like the guy above).

Awesome, thanks for the link! I'm not sure I'm clear on which switches are needed though. I've read that you need normally closed switches, and then I've also read that you need normally open switches. Do you know which it is? Also, what kind of wiring would I need to buy?

I'm really quite a noob at this stuff, but let me make some guesses. More knowledgeable people should correct me (how else will I learn?).

Since the pedal works with nothing plugged into the extra jack, I'm assuming that those circuit loops are OPEN when nothing's plugged in (again--I could be quite wrong). I would assume that to trigger each function you'd be CLOSING those loops (thus completing those circuits), so I'd find jacks that are normally open.

That's what I'm going to build. If it turns out I need the other kind of switches, I'm out under four bucks for the attempt.

Regular wire used in pedals and guitar innards should do: 22 or 24 gauge braided wire.

Hi

This is super easy and I've build one myself.

You need a stero jack, stereo shielded cable (2 cores plus shield) and two normally open momentary switches.

I used DPDT momentary.

Wire ground to the outer lug of the switches. Wire the tip to the inner lug of one switch, and the ring to the other switch inner lug.

Works a treat. One switch does either tap tempo, or stops the loop that is started by the main footswitch on the rc3. The other switch if tapped moves the patch one up, and if held for 2 secs or more starts to scroll the patches down.

Naturally if you want to use the other lugs to add LEDs you can, you'd maybe need a larger enclosure than what I used, or add a psu. For me it was unneeded.

Here is mine plus schematic...

Note that I used cable ties to secure my cable, and wound in a few more inches incase I want it longer In the future. An alternative is to have a switch craft jack and wire up or buy a stereo cable to plug in.

I used DPDT momentary.

Wire ground to the middle lug of the switch. Wire the tip to the outer lug of one switch, and the ring to the other switch outer lug.

Works a treat. One switch does either tap tempo, or stops the loop that is started by the main footswitch on the rc3. The other switch if tapped moves the patch one up, and if held for 2 secs or more starts to scroll the patches down.

If you need pics just ask.

Just finished this exact same project about 2 weeks ago. A huge money saver is using (2) 1/4" to 1/8" stereo jack converters along with a 1/8" stereo cord vs. buying the 1/4" stereo cords.

I used shielded cable like is standard for high gain pedal builds. The stereo 1/4" jack was less than $1 on tayda.
