heh, edder just did, with the "delay" for the launch of his fuzz pedal
perhaps if for a real delay pedal, perhaps a digital delay with some specials which make it stand out instead of the simple mix time repeat features which is the most common controls for delays(if wanna simple, there are too many to choose from, doesnt matter if its local or foreign made delay). Heh, forget bout cost, make it over the top with useful features(instead of all the cosmetic thingy, paintjob, blinking led etc which doesnt do anything at all, musically). Imho, the below i is like
1) digital delay with hi cut mode, tap tempo(common feature, but useful)
2) effect loop(throw any pedal inside the loop, ring mod, phaser, chorus, octave, you will get repeats of ring mod, phasing, chorus, octave etc)
3) dual delay circuit with individual parameters control with the special add on of ability to mixed this 2 delay either in series cascading style or parallel delaying via stomp switch
or expression pedal control for blending 2 delay in parallel
4) expression control for all the parameters(ala moog style). This one give player hands free choices to control whatever they want on foot
5) slam control ala sib mr echo style(no idea hows sib got it though) but i like the action of the slam control on mr echo.
heh, perhaps can based on the pt80 diy delay project and expand from there..
