[sdiy] a simple request: new Deluxe Memory Man schematic drawing

I know it may be a bit much to ask, but I don't really have the skill to do 
it, but here's my request:

Could someone do another rendering of the EH Deluxe Memory Man schematic?

The one I find (and it's the same exact one everywhere - I find it hard to 
believe that that would be the factory schematic) is hard to follow, mainly 
because the MN3005's are split up into a bunch of little sections. Doing 
that only makes sense with logic gates and op-amps. It being in 2.35:1 
anamorphic panorama doesn't help much either.

Nothing urgent really seeing how I have 2 DOD R-870's. Sure it's 2 1U high 
rack units and takes up much more space than a Memory Man, but I have two 
modulatable MN3005 analog delays (SAD512D if I want to use the "Flanger" 
mode, but since I put in bigger timing caps, it's more like a chorus that 
you can regenerate positively and negatively). I use a small mixer so that I 
can daisy chain them from a 100% wet channel and regen from the 2nd delay 
back to the first. I remember when I got the first one I thought, "This 
thing is so cool I need to get another one!" So I did.

I guess what I'm getting at is I'm not likely to be making a DMM clone any 
time soon, but I imagine there are others who can't be bothered hunting down 
old DOD gear to tweak like I like to do and would want a nice. easy to 
follow schematic.

But being able to modulate a long delay is a way cool effect. I use a fast, 
low-depth modulation to render what I call "Slabrato" - a portmanteaux of 
slap-back & vibrato (if you couldn't guess...). I think a flaw that works 
out to be a feature is that the LFO tends to modulate the biasing of either 
the BBD input or some other area that gets biased so you end up with a mix 
of slight tremolo with your vibrato. Only thing missing is being able to 
control the delay externally.


cheers,
