EHX Double Muff

[Craiz]

After a ton of searching, I finally found a schematic for the double muff. here ya go.

Anyways, I can't read that at all. Yeah, I can match most of it with the Muff Fuzz schem, but the changes (No, it's NOT just two muff fuzz's, there are some differences) escape me completely.

If anyone has a bigger/clearer schem, or can read those little numbers, that would be fantastic, thanks.

There are multiple versions of the double muff, just so you know. I just fixed one for a guy in town, and his was different than mine.

[Craiz]

I didn't know that, actually. I know that there's a transistor and an ic version of the muff fuzz - does that also apply for the double muff?

[eatyourguitar]

the new muff fuzz is SMD except for the two 2N5088 that are through hole TO-92 package. its nothing like the big muff.

[Craiz]

Yeah, i heard the new one sounds completely different. I'm reffering to the originals- the ones in the little boxes w/o a foot switch.

And no....they're not like big muffs at all......

[eatyourguitar]

try looking at this. they look close enough. just double it up.

I have a lot of 2N5133 and I don't think they are all that special. just use the 2N5088 and tweak your caps as needed for a sound you like.

Think were on different pages......

The Double Fuzz is NOT just two Muff Fuzz's.

So, like I was saying in the OP, I have the schem for the double muff, I'm really just wondering if anyone has a larger/more clear version that would be easier to read.

As far as I know, there never was a double muff in nonfootswitch boxes. There were two versions of the original muff fuzz, as you said, IC and transistor. The double muff is essentially, 2 muff fuzzes in series. The few extra parts, I assume, help shape the circuit, provide filtering, etc. It was discontinued a few years back, but EHX re-released both the muff fuzz (overdrive), and double muff with their xo packages.

I've been messing with a literal 2 muff fuzzes in one type double muff on the breadboard. It's a fun one.

Here's the guts of the two different DMuffs I mentioned. Obvious thing you'll notice is the layout...then the use of 5088's vs bc550's...the switch pcb...I think the values are the same. The right one is mine, and it use to have another cap+res in between the black leads from switch and board.

3 if you count the new SMD one with 2N5088. lots of people have posted the real [double muff] schematic but it always gets taken down. Aron Nelson said DIYstompboxes can't host the file after EHX asked him not to. all the strip layouts were on whack bullshit free image hosting sites long ago. all gone. I'm still waiting for the schematic. its not on FSB. its not too hard to guess those values even though its blurry.

I mentioned that one too when I said they were re-released in the XO packages. I will draw a schematic for this in the next couple days, and send it to the interested persons. Not going to post it publicly though...gotta show a little respect right?

ctrl + mouse scroll in.

You can read the values for the most part.

Jero - if you could PM me a copy of that, that would be fantastic.

Just to be clear, though - this would be a schem of the original DM, and not the nano, I'm assuming?

Anyhod - thanks.

Did you see the picture I posted? That's where the schem would come from. There's no way I'm going to bother myself in tracing smd even though they would be the same thing.

[Craiz]

Oh good. Just wanted to make sure. And hey, thanks again!

The plan, if anyone's interested, is to modify the DM to taste, place a simple boost in front of it (probably an LBP variation), and put a Stupidy Wonderful Tone Control on either the first or second muff, I'm not sure yet. Should be fun.
