Some tips for circuit bending the Digitech RDS 7.6 digital delay time machine. This one is from 1987. There's a lot more bending points on these old vintage delays than what is shown in the video but these are some basics to get started.
Hey, this is an amazing bend. Do you have any more details about the R85 resistor mod? Can't find the video you mention on yt. I have a DOD DFX9 I'd like to perform a similar mod on and was thinking maybe it would be the same (re continuous sound when changing coarse delay time). Thanks!
Hi, all I did on my RDS 7.6 system is cut one end of the R85 resistor and that did the trick. Did not need to cut the D3 diode like some other people have done. Not sure about a DOD DFX9 delay. I'm guessing it probably has a similar diode. The Boss DD-3 I had did not have any drops between adjusting the delay time ranges. Some delays do, some don't. I would personally make a test probe with a 10k resistor in series and start poking around with it, shorting diodes out just to see what happens, but that's just me :-) I assume no responsibility for any damage.
try U40. but I actually ended up getting a better result by wiring a momentary switch across the delay time pot. If that works good, then wire ANOTHER momentary switch across the feedback pot.
@@droneopt Ah, OK. Thank you! I"ll try the pots. Just so I'm understanding. Momentary across the delay time pot (shorting it), and then as an additional mod, do the same for the feedback pot? I have a 7.6 if that makes a difference. I've done all the other mods I've found and they are working great (delay spill/R85, ram and binary counter switches,5k pot to 10k pot). What does shorting the feedback pot do?
