This is the PCB and Panel to build the #2399 TRIPLE SPLASHBACK DELAY.
A module designed around 3 PT2399 Chips in a rather funky configuration to make anything from a tight echo near chorus, to swathes of delay and reverb all the way over to absolute unimaginable garble and never repeating chaos.

It is in KOSMO format and does require self assembly, please check the product page for more info!
