Title: SAD1024 - List of vintage pedals that use it
Post by: MoltenVoltage on July 21, 2010, 11:08:38 AM
I really want to get an SAD1024 chip but am not about to pay $79.95 + shipping - the current ebay price.

So the plan is to get a vintage pedal, pull the chip and put in a socket so I can try some other designs, but still use the original pedal.

Here are the vintage pedals I am pretty sure use it:

- EHX Electric Mistress
- Ross Flanger
- MXR Analog Delay - but NOT the M-118 version, I am pretty sure it was called M-117

anyone else know of other pedals that definitely use this chip?

the ehx polychorus, mxr flanger and mutron flanger also use it. 

i think you'll find that you could have a hard time finding a used pedal w/ that chip for less than the going price of the chip.  i know because i tried; ended up buying the chips themselves.

let me know if you don't have any luck as my seller might have a few left.

+1.  It's a shame to rob the chip from another pedal.  If it's for a DIY project why not use the MN3007 adapter?

A while back I almost bid on a Ross Delay which I think had three SAD1024As in it.  The price ended up over my budget.  

Although I have one in my A/DA flanger clone, and it sounds great, I agree that it makes more sense to retrofit an MN3007 for any new builds.  Plus the MN3007 has a bit more headroom.  On a side note, I thought I might have killed it the other night when I was making adjustments.  Scary thought!  Did accidentally kill the op amp following the BBD though.

Not planning to "rob" it, just "share" it with another pedal.

The reason I want the original is that I want to hear how this fabled chip sounds, and also there are some layouts already around for it.

Do you have a link for this MN3007 adapter?  Is it a separate PCB?
Title: Re: SAD1024 - List of vintage pedals that use it
Post by: 12Bass on July 21, 2010, 11:52:17 AM
What pedal do you want to use it in?

There's another list here:  http://www.vintagechip.altervista.org/ICs/sad1024.html

As for the sound, it may depend on the application.  The SAD1024A is probably one of the best chips for flangers due to its wide delay range and extended bandwidth.  However, CMOS clocking/buffering will get an MN3007 up to practically the same level of performance.  For chorus/delay, other chips make more sense.

There are several incarnations of the MN3007 retrofit.
Depends what pedal you are "borrowing" the SAD1024 from.
And what pedal you plan to "share" it with.
Search for the A/DA 3007 retrofit thread and the EHX/EM 3007 retrofit thread.

You could buy 2 sad512

.... I guess SAD512 is way more difficult to find...

here you can find my schematic to convert MXR flanger with MN3007.
It's tested and working.

The SAD512D (used in the MXR Micro-Chorus and others) is impossible to find.  The SAD512 is a little easier.  It's basically an SAD1024 with just one working section.  You're supposed to hook the 2 sections in parallel when using it.

I have been looking for a schematic for the Micro Chorus for quite a while, does anyone have a link to the schematic? I thought I remember seeing it on the web several years back, but recent searches have not been fruitful.

I have to search for it somewhere 'cause I had to revise it, since that pictured there was a prototype, featuring two options: with or without the tranny.. (I opted for "with the tranny")
I can provide this guts picture, you may trace it down :

sorry to nekro bump this thread, but i have been looking forever, and i can't seem to find this here adapter project..
can someone please buy me a clue?
i need to adapt a sad1024 eh  clone theory to an mn3007 instead, and i can find threads that reference it, but no layouts or schematics.
help appreciated!

Look at the Mutron Flanger Dissected thread.

Digi2t (Dino) made a vero layout:

http://www.diystompboxes.com/smfforum/index.php?topic=103542.100

and I made a etchable board layout.

http://www.diystompboxes.com/smfforum/index.php?topic=103542.120

Let me know if you need any help.
Do you know if the clone theory's SAD1024 uses 512 stages or 1024? I haven't looked at it myself.

larry, you rock. ;)
thank you!! i will definitely need help, i'm sure. cuz i suck. ;)

i don't know if they use the full chip or just half. i'm kinda hoping i lose on an auction on one of these so i don't have to deal with it.
tony forestriore hooked me up with a SAD that went in my ross flanger... trying to find another is gonna be next to impossible, but i DO have a mess of mn3007's still... so this is awesome... thanks bro.
i've been going thru threads trying to find info, but a lot of it is way above my pay grade.

I'm multi tasking....finishing up the Mutron Flanger.......Stephen Giles hit me with surprise board shots of a stereo, dual delay section flanger that I've been wanting to build.

Can you link a schematic to the Clone theory that you're repairing? I don't know if there are different versions of it.....knowing EHX...most likely!
Title: Re: SAD1024 - List of vintage pedals that use it
Post by: armdnrdy on October 05, 2013, 04:33:17 PM
I took a break and found a couple of schematics for the Clone Theory.
One is more recent and takes a MN3007 and the other is from 1977 which is loaded with a SAD1024.
The SAD schematic shows the BBD used in series for 1024 stages....same as the 3007!
Jimi......you're in luck!

Now,
I'm going to need some shots (clear) of the area (trace and component side) around the SAD.
Once I have those...I can design a daughter board that will work for this particular circuit.

The problem with a "one size fits all" SAD to MN daughter board is.....there are many different ways to go about implementing the BBD IC to a circuit. From manufacturer to manufacturer it varies.

Yes, that's the beast but I got the impression that it was for increasing the stereo ambience. How dare he put a synthesiser through it - perish the thought!!

I should think with some tinkering and slight re-routing that could be turned into a decent TZF.

i didn't win that auction, i've got enough crap... lol... til the next "gotta have" arrives.

gotta ship a suzy q to alaska, then start on the rhythm and sound...

but i think i may try and put this together, and see if i can pull the sad1024 from the ross flanger and save it for antiquity. ;)

you guys are the best. ;)

Dino's perf and my etch board are for the Mutron Flanger.

Each circuit would have to be implemented in a slightly different way.

I'll take a look at the Ross Flanger schematic to see what it would take to make a daughter board.

For those that are searching for SAD512D chips; they're in the Coron CS-1 Chorus and FG-5D Flanger pedals. The Coron delay has a SAD1024A chip, just like the Jet Flanger and Flter Matrix.

The Scamp S24 Time Shape module has four of them (I sold a buddy two in order to resurrect his unit).  But if you can afford one of them, then the price of SAD1024s is the least of your worries.

That's one of those cases where it's entirely appropriate to cannibalize a piece of vintage gear.  The SWTP unit was..."interesting" for its time, but it didn't really do anything that a Coolaudio V3205 couldn't do now.  Those Reticons can be put to MUCH better use.

Good find!
