The only problem I have is that the flashing LEDs aren't 100% in time with the delay. I built it into a 1590BB (see video above in the post) and it was pretty crammed with wires.
Hell, I don't think I'll even have the flashing LED for my pedal (just a maybe). Some people might like to have all these switches as options. So get your Deep Blue Delay tapped up for ultimate TGP mojo points! :o) Manual Time and Depth (modulation) controls are dealt with on the daughterboard and so switches are included for modulation, double time and delay scale, along with the tempo clock control (tap tempo using a momentary footswitch). You will need to remove the Delay/Time pot from your effect, and the daughterboard then connects to pin 6 of the PT2399 to control the delay times. A datasheet for the Taptation chip can be downloaded from here, and notes about interfacing to the PT2399 can be downloaded from here. This is a daughterboard for the Taptation kit you can buy from Aron at here (which includes the Taptation and digital potentiometer ICs), and will allow you to add tap tempo capability to any PT2399 delay pedal.
But I am leaving this here now so the information remains available for anyone wanting to build one.įor anyone starting a new project I would recommend looking at a product like the Tap Tempo kit from UK Electronic which is considerably cheaper, smaller and comes with all the parts you require in a single kit.
Update 10th September 2014: I had dropped this layout from the blog because there had been instances where people had been unable to get the IC, but more importantly I think there are other methods to do this now that are cheaper, much more compact and the kit comes with the required IC AND a PCB which I think is a glaring omission considering the price of the Taptation.
