So why doesn't someone become a distributor for the parts needed? Someone who can source the parts and peddle them here.
You could just package it as a Super Everdrive DSP Kit.
I tried forever to get a Super Everdrive with the DSP installed and barely missed the stock every time. I found a non DSP version and jumped on it.
If someone had offered such a kit with the DSP, Clock, 74HCU04 and an instruction card, I would have paid $20 to $25 for it, easy.
