Tipps & Tricks: DIY Mini Tap Tempo Controller

Mini Tap Tempo controllerI guess almost anyone who uses one or more pedals with tap tempo on his pedalboard have thought about a device that is able to tap several pedals at the same time.

Enclosure

For my DIY mini tap controller I chose the smallest Hammond enclosure. Ideally it a pedal like this should only need small space on my pedalboard which is almost overcrowded anyway.

Switches and jacks

For the footswitch I drilled a 0.47” hole in the top and two 0.35” holes for two jacks in the front of the enclosure.

The footswitch is a DPDT switch with 6 pins, so both jacks can be wired separately. I use a mono jack (the standard tap for most delay pedals with external tap tempo) and a stereo jack (for Strymon pedals).
If you use two mono outputs, you can also use a simple footswitch and separate the two jacks by adding a diode.

Additionally I installed an internal little switch for the mono jack to alternate between “normally open” (suitable for most pedals) and “normally closed” (Boss standard).

I lacquered the enclosure with white color and installed the switch and the two jacks.

The wiring

Wiring tap tempo

For a safe stand I glued rubber feet to the bottom.

The switch works very precisely and can be tapped easily.

In a bigger enclosure you can also use several mono jacks (but just like I wrote above, these will have to be separated by diodes).

This small project is done simply is recommended for every delay nerd.

If you want to install such a switch you will have to connect the tip of the input jack with the pin in the middle of the new switch (this one must have three pins – you will need an on/on switch).

After you have connected each of the outer two pins of this new switch with the outer pins of the x wing foot switch, you will have to connect the pin in the middle of the x wing foot switch with the shaft of the mono jack.

Now you will be able to switch between “normally open” and “normally closed”.
