I need boss dd3 schematic

[cd]

OK, by dinking with the voltages going into the controller, I was able to get up to 1.7 seconds of delay time.  I know what you're thinking - yay! BUT at 1.2 seconds and above, you start to get some real nasty digital noise.  I know again what you're thinking - fine, just increase the pre and post filtering - well, then the tone starts to suffer big time (no highs!)  I was able to settle into a new max delay time of 1 second, which is a compromise between least noise and good highs with the stock filtering - though of course, the stock 800ms second setting sounds best to my ears.  You can do this with the usual internal trimmers - of course if you bugger up you're pedal, that's your own fault, not mine.

OK then, what's the next step if you want more delay time - add RAM of course!  I have a line on the exact 4x64k RAM used in the newer DD-3, however there's a $100 minimum order involved so no dice.  And I'm not going to bother cobbling together a group buy because frankly, you might as well mod a DD-5 or DD-6!!
