I built a tap tempo switch for my new DD-20 this morning during my conference period. It took about 5 minutes, and most of that time consisted of waiting for my soldering iron to warm up. I bought a small square Hammond enclosure (1590LB), a DPDT momentary switch, and a mono 1/4″ jack. I ordered this stuff from Pedal Parts Plus and had them drill the enclosure for me.
All in all, it cost about $15. I could saved 3-4 bucks if I had bought a plastic switch from Radio Shack and drilled the enclosure myself, but I wanted a heavy-duty switch (since I’m a little lead-footed) and I don’t have the right size drill bits to do my own drilling.
It works perfectly, and I can tell that it’s going to make using the DD-20 a lot cooler. For one thing, it’s impossible to use the built-in tap tempo and change presets without a 2-second delay. 2 seconds is forever in the middle of a song.
Here’s a pic:
Here’s how it looks on the board:
And here’s the gutshot (kinda sloppy soldering job, but it’s not carrying audio):
