PT80 COMPLETE KIT

This is the best DIY digital delay stompbox kit on the internet.  Warm, quiet, beautiful echo, patterned after the Ibanez AD80 analog delay unit.  This project  emulates the old-time analog delay unit, in this case the Ibanez AD-80 vintage stompbox, with a modern digital delay IC. The results are excellent and you won't know it's not 100% analog. The general design of this circuit is almost the same as the AD-80 except the bucket brigade ICs are replaced with a Princeton Technologies PT2399 delay/echo IC and the electronic switching is replaced by a 3PDT stomp switch. The compander IC gives it excellent noise specs and also contributes to the great analog-like sound of it. A charge pump is on board so that it has plenty of headroom from a single nine volt battery. The charge pump was not part of the original AD-80, but is a modern bonus in this project to save on batteries and be able to use a typical stompbox wallwart power. Click here for more general information about the kits.
