found an old DOD comp/ Dist...what can I do with the following IC's?

[B_of_H]

My Mom called and said "I found one of your old guitar things down in the basement and I dropped it off at your house"

So I got home from work and it was a DOD 'attacker' which was a comp and distortion that I must have bought when I was a freshmen in HS.  Anyway I opened it up and immedeatly saw the CA3080E (I know what to do with this one) but didn't recognize the others.

They are labeled:

MC14007UBCP
FFRO 9301

TL064CN
99006

M31AG
LM1458N

Any ideas?

Also, is there anywhere I could possibly find the schem for this?  (longshot I know)

Schematic: http://filters.muziq.be/files/schematics/dod_fx54.gif

The TL064 is a quad op-amp (counterpart to the common TL062 dual), the LM1458 is a dual op-amp, and the 4007 is a digital IC that's part of the electronic switching.

Awesome!  Now I can at least know what resistors and caps I can salvage and where to look.

This is actually a pedal worth salvaging so don't butcher it yet.  Although DOD did not do so, the compressor and distortion section can be separated and made separately adjustable; a "multi-fx in a box".

interesting, I hadn't even thought about that. 

That sounds like a big hack job though.

I say:

Just fix it and play it.

If you can't I'll fix it for you (charges for labor and parts apply).

Give it to someone who'll give it a good home.

Use it as a paperweight.

Anything, but it's worth far more than a couple 89 cent ICs.

Agreed.

Like Mark mentioned, you can separate the 2 FX.

Yes.
Save it, don't scrap it.

if the OD sounds like arse, you could also just rebox it and use the comp side by itself, and ignore the OD.

1) The compressor part is a cousin to the Dynacomp, more or less.  That means you can do all the usual Dynacomp/Ross mods, like adjustable recovery rate for more sustain or quicker limiting.

2) The distortion section is a cousin to the op-amp Big Muff, more or less, so you can monkey around with clipping diodes (looks like a job for LEDs if you ask me).

3) The tone control is a cousin to the Big Muff tone control, so you can read jack Orman's article on presence and tone controls over at AMZ and get some ideas for mods.

4) One of the rather peculiar things about this pedal, if the linked-to schematic is to be believed, is that the dry/clean signal is NEVER absent.  That is, even when the compression and distortion are on, there is always some clean unprocessed signal at the output.  And as near as I can tell, the processed signal is not outof phase with the unprocessed signal at the output, so there is no fancy-schmancy cancellation. 

5) All of this means that you have an excellent test platform for a whole batch of mods whose effect you can learn from and apply to other things you might build in the future.  If you were smart, you'd stick this in a 1580BB and buy yourself some toggles.  This one's a keeper.

I should emphasize that I found the schem by a routine search, and have no direct experience with this pedal in particular.  However, DOD schems do seem to be pretty widely available, so I'm guessing it's probably reliable.  In any case, I agree that it would be a shame to butcher the thing for a few bucks worth of parts when there's probably a lot of mod potential (and a groovy enclosure for a diy effect, if this one gets rehoused in a bigger box as Mark suggests).

Sell it to me! I'll use it as it is right now.

Ok, 'pedal-huggers'

You've saved this stompbox.  I've got a BB sized box for it and I'm going to do some poking around and try to see what I can make of it.

Thanks.

I didn't even have time to print the "Save the FX54" T-shirts

Soons I saw those pics, I was like...no, that's much too cool to just tear up for a few this's 'n that's's.
  You've saved this stompbox.
  Nice looking board, I'm sure you'll figure a way to make great use of it.

Now that i've agreed to keep the pedal intact I hope everyone is ready to help me out with getting it up and running.  I'm going to take some detailed pics and post a list of questions.

We'll talk soon.

I'm calling you tonight about this. 

[cheeb]

Now I want one...

So it doesn't work now??
