A tap tempo pedal (to be used with a DD-5 or DD-20, for instance) is actually exactly the same as a keyboard sustain pedal, so if you have one handy, you can start tapping right away.
To build one, all you need is a momentary normally open switch (such as this one:
...plus a mono jack and a suitable box. Connect the two soldering tabs on the jack (tip and sleeve, respectively) to the two tabs on the switch (either way will work), and you're done. You can then use any regular patch cable to connect the switch to the pedal, and tap away.

Can I incorporate a single momentary NO-SPST & "split" its output into two mono jacks to simultaneously control the tap-tempo of two BOSS pedals (namely the DD-5 & the soon to be released RC-2)?
A separate switch for each pedal's tap-tempo may be required if the two pedals fight each other for the signal but I'd rather use a Maplin's momentary DPST or DPDT momentary switches if a single SPST won't work.
I was thinking it would be a good thing to control many tempo-capable pedals with the same foot taps rather than trying to set the tempo for one.. then another.. etc.

I don't know if you can just split it to two pedals. The switch only opens a path to ground, which the pedals obviously share, so that's not a problem. But you might might get some strange interaction since you also combine the control outputs (the ones the switch sends to ground when you tap). I just don't know what - if anything - happens there. It might work just fine, or it might really confuse both pedals...
Using a momentary DPST or DPDT would allow you to keep the control outputs separate until you actually tap the pedal, which might be an advantage. But as I said, I don't know if it is neccessary.

| I was thinking about turning a useless or empty boss pedal chassis into a momentary tap tempo. What would I need to do there? |

Hmm, you know that's a good idea. Something I could actually use my dead PS-5 for!
Stinkfoot, can you help on this one? Assuming the Boss switch under the pedal is good, can that be used as a mometary somehow or is that too much work?
I'll try to crack open my FS-5 pedals over the next few days and check them out. |

The switch in Boss pedals is a momentary SPST, so it should work fine for this purpose. Just wire it the same as you would any other box, and it'll be fine.

Yep, just the same way. You can even use the existing wires, to avoid having to solder on the switch itself. Follow the black wire and see where it ends up - if it is connected to one of the jacks, you only have to reroute the purple wire to the tip of the jack you're planning on using as the "output", and you're done. If the black wire ends up at the circuit board, you will obviously have to move that one to the jack as well (sleeve connection).

| Awesome, thanks a lot. I'll let you know how it turns out when I get around to it. |

Ok, I now have what I refer to as my TT-1. I didn't really like the HM-3, so I gutted it and did as I was told earlier in the thread, and it works. I'd take pictures, but my nice camera phone died. :/
It's black. It has some holes needing to be covered somehow. I scratched off all the letters with a coin (works really well), and I just left the orange <- pointing to the jack on the left side (the one I used).
Thanks, guys. |
