From the vendor
Here’s one insane fuzz/noise machine invented by Anchovie at the diystompboxes forum (original thread here). This one uses a PT2399 to add in all kinds of mental sounding fuzz – all we can say is…build one!
It uses a DPDT momentary footswitch to engage a feedback loop…which brings in a whole world of craziness!
