I need your help! (Rare Electro Harmonix Gut Shots Wanted)

Post by Scruffie »

I've been asking around at the moment for anyone that has and can provide gut shots of any of these vintage Electro Harmonix pedals with the intent of putting projects out there for DIYers and bringing them back from extinction, it'd be very much appreciated if you could help me out or know anyone that can :)

If you have any of these pedals, please let me know:-

(Original 70s & 80s Versions Only, Not after the modern Tube Versions XO etc. that are still in production)

EHX Full Double Tracking Effect
EHX Slap Back Echo
EHX Silencer
EHX Zipper (Not Tube)
EHX Pulsar (2 Knobs & Switch Version)
EHX Black Finger Sustainer/ Compressor (Not Tube)
EHX Y-Triggered Filter
EHX Space Drum
EHX Super Space Drum
EHX Rolling Thunder
EHX Clap Track
EHX Crash Pad
EHX Panic Button (Have some shots but more never hurt)
EHX Sonic Boomer
EHX Random Tone Generator
EHX Deluxe Octave Multiplexer (Have some shots but as above)
EHX Bad Stone (Not urgent, already have a working project, just interested to see the differences)


Cheers! :yay: :hug:

I did start a thread on another forum yes, but not on here I don't think... If I did start it here I forgot and didn't mean to double post.

There has been some development... I have verified projects for the Bad Stone & Full Double Tracker up and running plus schematic redraws of many of the Hard to read EHX Factory schematics, it's all a work in progress and large undertaking especially with alot of the pedals needing conversion to more modern available parts and easier power supplys and also the Factory Schematics possibly differing from the finished design or having Mistakes Purposely put in (Which is why I need gut shots to verify the schematics) but i'm keeping at it, after hearing a demo of the Attack Decay today, i'm very much interested to get an adaption of that one working :cool:

Oh yeah, I remember now, it was on a diy-focused forum :)

So, that's a great project.. You might even get EHX interested I've read somewhere they asked a guy to analyze his vintage headphone-amplifier for their new version..

That or get a cease and desist letter :lol:

Yeah it was on a more DIY-focused forum :thumb:

I don't think they're interested in bringing back these more obscure pedals, even if I am! They're probably not mass marketable enough to bother with and the reason they're so rare is probably because they weren't very good sellers in the first place.

If they wanted them back, the original designer of alot of them is still in work (Howard Davis) he designs for Pigtronix now, i'm just having a bit of fun and trying to get them back out there being used for people that can't afford $500-1000 for a pedal that cost $130 new, if they can even find a working one! Collectors may have soured the market slightly there and I doubt alot of them are now gigged which I for one feel is a bad thing, those interesting sounds should be out there.

Please, they'd be very much appreciated, both sides of the board if possible in macro or scanned form (you probably know how to take good pics, just lettin' people know the sorta thing i'm after).

Just remembered that on the EHX forum there is a guy calling himself The EH Man, I saw pictures of his collection and it seems he almost has anything vintage EHX..(can't find them unfortunately)

Contact form on his site: http://electroharmonix.vintageusaguitars.com/index.php?option=com_contact&view=contact&id=1&Itemid=18
Don't know if he does this kind of thing of course..

He's on the DIY sites too... I imagine he does have the pedals but as he makes money from them and also works for EHX, probably aint too open to sharing this sorta information, otherwise he'd be like an encyclopedia of all things EHX!

Yeah, that's RonSound. He sells schematics on his site, and says that he may be willing to help if someone needs the value of a component or where connection runs, etc. He could be someone to go to if you're stumped about something. It might also be worth investing in a schematic or two from him, since it may be just what it takes to crack open that vault. :idea:

Well, he knows i'm doing this, I think he even bought a Bad Stone board or two, he can chip in on one of the threads on the other sites where he hangs, but I think he's probably a busy man (Admins EHX, Has his Big Muff Clones, Runs a Schematic Selling Site, Offers free help to people with broken pedals, Restores Broken Pedals, Life etc.)

I actually have most of the schematics he has I think, infact from the above list i'm only missing schematics for the Panic Button, Rolling Thunder, Pulsar (I have the Tonepad one, I mean Factory) Random Tone Generator and I need a more Legible copy of the Attack Decay (The one I have now he actually posted up himself) but these schematics can't always be trusted, aren't always readable and sometimes have mistakes/parts missing, also EHX used whatever parts they had to hand so a design compared to an actual unit could vary a fair amount and buying schematics isn't an option for me, this costs enough to try and bring them back already.

I don't want this to sound like I have anything against him or anything though! He's a nice guy, but this is his bread & butter and I just don't think helping me clone these things is in his interest, time wise if anything, I may ask him if I get stuck but hopefully I can work it out on my own, i'm getting there, that's why I Need the gutshots though, just to tick things off the list and also help keep posterity. Maybe down the line i'll contact him once i'm passed this initial stage of information gathering, I hope he'd like to help and enjoys the project himself as a man that likes all things Electro Harmonix.

This is only the first step though, once i've got verified designs, I have to rework them to modern available components so that they can be built by anyone and for a while to come. Which reminds me though, if anyone is electronically savvy and can breadboard, design/etch & test PCB layouts or trace for me, that'd be a big help, I need as many people as I can really to try and start cutting down the load...

Working on my own designs as well as an old pedal or two right now, but feel free to hit me up when the time comes. You know I'd love to help any way that I can.
