    Anyone every performed the Boss DD20 mod where you drill a hole and wire up a switch to feed the tap tempo jack on the back? Any instructions or advice? I'm considering this instead of an external tap tempo box.

    Use a drillpress (or mill if you're feeling fancy) for pedal mods. Easiest, quickest and cleanest. And use machining oil of course.

    Before. You start drilling you know you can already use a tap tempo with it right?

    Yes, if you hold down the right pedal for 3 seconds... but that's too hard to use.

    near the top of the right pedal... kind of looks like a boss true bypass mod switch.

    I think that it's physically possible, but I'm not sure how it would be more convenient than an external tap.

    there is no need to drill, the CTL jack on the back of the pedal is for an external tap tempo switch. I use a cheap momentary switch that used to be for punching in on my 4-track. Any momentary switch will do, and it works soooo much better than the ridiculous way you have to access it on the pedal itself.

    what I want to know, is has anybody modified the CTL jack to actually function as an Expression pedal jack that can control the Mix or Repeats??

    Yeah, I've seen some people hook up a Boss FS-5L external foot switch which can be used for tap tempo. It hooks right into the back of the pedal.

    Yes, I'm well aware that there is an external tap tempo jack on the back of the DD20. In order to save the space on my board, I want to mount the tap tempo into the right foot pedal of the DD20. I've seen a photo of a TGP'er who has done this... but I am looking for details how this should be wired internally.

    oh gotcha. my external switch is not on my board, off to the side. good luck!

    I've got to admit they really screwed the pooch on the tap tempo thing. The DD20 would be the perfect Boss delay if it had better (ie usable) built in tap, external expression control of mix or feedback, and replacing the twist or whatever effects with something useful. Jutst MHO of course...

    You want to use a momentary switch, and connect it to the external tap jack. Must be connected in a NC (normally closed) config for the DD20.

    Yes, you can wire the switch directly to the lugs or whatever the jack as (may be pcb mounted), or you can figure out where the jack is wired to (again, this may be pcb mounted so it may be the same place). Test it to see which is hot and which is ground (tip and sleeve respectively) and wire directly from the corresponding lugs on the momentary switch.

    Sounds like a cool idea actually. But might you run into problems due to the fact that the CTL jack can actually be used for three different purposes (on/off, tap and preset change) according to how you set it? I guess that wouldn't change anything really....

    That shouldn't matter, just set the function of the control jack to 'tap tempo' or whatever it's called like you normally would with an external tap. You could actually use this switch to perform any of the functions the ext. jack will accept, while still using the foot switch on the pedal for a second function.

    This. Just means your new "tap tempo" switch can actually do 2 other things.

    Not sure how and where I'd solder wire to these jacks.... I'm only familiar with the simple metal one's.

    Crappy - you might have to use the underside of the board :/
