Title: i miss my DOD Grunge pedal.
Post by: pazuzu on April 09, 2010, 12:30:49 AM
it was my favorite solid state distortion ever, i had it for about 7 years, and then met a fitting end to such an illustrious career.

anyone got one for sale, even a board to rehouse would be awesome. :icon_mrgreen:and yes guys, i am aware of the boogie, got one. just want a blast from the past. i am looking for a model form the nineties, not the new version.

I've always wondered, is there a difference? Besides the "cabsim" output, of course.

i don't rightly know. i tried a new one at a guitar center and it didn't sound the same to me.

There are a few out on ebay.

Seriously?!?!

I have always looked askance at it because of the name.   Same thing if it said "punk" pedal, I guess, LOL.
And the buzzsaw sound wasn't what I liked at the time.

They're pretty ubiquitous at the GC and Craigslist around here.

Pyrotechnical mishap?

I'm guessing it was beer-spill related.  Reference the cover of Mudhoney's Superfuzz/Bigmuff.

yea, i spilled a pitcher on it. back before i knew how to fix such things. we played baseball with it afterward.

actually it doesn't look too complicated...

Are the good sounding ones the older ones with the smaller footswitch, or is that not a good indicator?

I'd build one too if you made a good perf layout or PCB from the Schem. I suck at doing that, or I would do it myself. I have to buy RG's book one of these days...

yea, the good sounding ones were before they went with the boss style case, but the switch without the visible socket head allen bolts. i found one on ebay for 20$ shipped, just payed for it. :) for that price it was just as effective to buy it as opposed to time and materials to make one.

Do you still have it? I'm sure it can be resurrected.

I'm a little confused, the smaller footswitch version with the allen head bolts is the OLDER version, so really you like the later one with the larger footswitch (actually the plastic part you step on)?.  For instance, the one in the picture you posted is the newer version.   Why do you prefer that one?

well, actually it was the model that was out when i bought mine, the allen head version, i never heard. but the new ones look like boss boxes, and do not sound the same to me.
but just to reiterate, i found one on ebay for 20$ shipped, so i'm good.
thanks for all the replies people.  :icon_biggrin:

I know what you mean now, when you say the new ones look like Boss pedals you're talking about the DIGITECH Grunge pedal.  I didn't even know Digitech was making one.  I checked the Digitech site and saw it.

ahhhh, ok. aren't dod and digitech basically the same company?

Yeah, but I had never seen a DOD pedal that looked like a Boss, but finding out that you were talking about the Digitech-labeled version made my understand.  As I said, I didn't even know that Digitech was putting that pedal out now.  I wonder what they changed in it that makes it sound different?.

Post by: pazuzu on April 15, 2010, 10:05:59 PM
man, distortion sounds are sooo arbitrary, and i was comparing the new one to my memory of the one i had 10 years ago, so who knows maybe nothing? i'd be willing to bet it is just the quality of the components though.
Title: Re: i miss my DOD Grunge pedal.
Post by: pazuzu on April 16, 2010, 02:12:41 PM
i got it today, and it does indeed sound different, unfortunately it sound no where near as good as i remember. i busted it open and had a look and there are no micro components so i'd bet that's the difference, since everything put out now uses them.

here's a gut shot for anyone interested:

OK you have got me curious after looking at the schematic you posted and the gut shot...
What are the ICs ?(cant tell from photo) and the 9 Qs ?
Does the pedal you have correspond to the schematic you posted ?
And just a thought you could up-grade some of the components on the pedal you just got,and if its fairly old some of the caps might actually need to be replaced anyway.
Title: Re: i miss my DOD Grunge pedal.
Post by: pazuzu on April 19, 2010, 09:33:28 PM
all q's are 2n5088, except q1, 2, and 4, which are j201.

the 8 pin ic's read 456OD, and the 14 pin reads MC14007UBCP
                                                                        FKR9807

sorry, i have never built with ic's except for a cricket, so i'm not really familiar with them, as far as the schem i found i think it's the same one.

Post by: Brymus on April 20, 2010, 12:49:50 AM
Thanks,for that
I count 13 100k resistors in your pic but only 10 of them on the schematic.
Maybe I am making a mistake in counting or checking the color bands,if not then something is different,IDK
Title: Re: i miss my DOD Grunge pedal.
Post by: zombiwoof on April 20, 2010, 01:10:49 AM
I think a possible reason that the pedal doesn't sound like you remember is that it may have gone through a number of revisions, even slight ones, that changed the sound.  It's possible that only the certain version you had at the time sounded the way you like.  I know with many pedals that have been around for some time, companies change the IC type, and component values/types for many reasons, which may change the sound some.  Look at the different versions of the Boss DS-1, which has had I think five different chips in it, and players seem to like one or the other.

Good luck, I hope you can find one that sounds like your original one.

While the schematic does include the switching FETs (why?) and superfluous bypass buffer transistor, it omits the 4007 (?) and associated parts. I don't see any source of the 4.5 and -4.5 voltages either. So, counting parts is a no-go.

No offense meant to whoever traced it.

ok, scratch the original schematic than. it was just the first one i googled. as far as the idea that the one i had sounded better than the one i acquired is probably less likely, i am betting this pedal just sounded better to me when i was 22 and playing on a different rig. after all, the desire to get one of these pedals was inspired by a 12 pack of coors light anyhow.  :icon_biggrin:

here is a better pic of the guts, i have the pedal torn down, and i am not sure what i want to do with it. i only have 20$ into the entire works.
(http://i34.photobucket.com/albums/d149/pazuzu411/DSCF0596.jpg?t=1271774216)
i'm thinking to start getting rid of all the bullsh*t buffering and refitting it to true bypass. maybe replace all the caps with wima poly's or something? i don't know, i have never tried to mod a pedal before, but for the price this could be a nice project.

the fets are the 3 on the right of the set of 4 q's that make a square.
