Electro Harmonix - Percussion Effects Pedals (Schematics)

[Scruffie]

Hey All, New Here but i've been around a few other forums, some of you might recognise me.

Anyway, Hope this is the right place for this... had a bit of a difficulty working out the forum after I was pointed here by someone else.

I've been working on bringing back all the Vintage Electro Harmonix Effects and converting them to modern available components and here are all the vintage schematics i've redrawn from the hard to read originals:

(Can't seem to add pictures so i've just added links for now)

If you have any of these, or the Rolling Thunder Gut Shots would be appreciated, I also have gut shots of a Panic Button that needs tracing to provide a schematic if anyone wants to take the challenge.

Hope some people find some use for these!

I'm sure that the Space Drum circuit is correct - I got it from the designer!

Guys, I hate to be a killjoy, but considering EH still make pedals and stuff, has anyone contacted them to ask their permission for posting this stuff here?

Cheers.

Hm, EH post here, whatd'ya know!

Yeah, most forums have gone through a similar copyright discussion if anything at some point, i'm well aware, Photographs are fair game in my book, but it's not my place to say what's fair game for this forum, so to save hassle, i'll just remove them.

I was directed over here by someone else that suggested it as a plausible place where people might be interested in dissecting these old designs, but I am more frequent on forums where this sort of thing is less of an concern, when it was suggested, I sort of assumed it wouldn't be an issue, my mistake.

The intent is to modify the existing designs just to clarify, most of these use parts that are long extinct and the second hand market has soured most peoples chances of ever using the pedals, hence, conversion and the option for people interested in DIY to try them. So maybe once i've finished, i'll put them back up in there new forms, for now, so long.

Hi again,

Well, I don't want to stir up things or be a smartass, but the copyright/ IPR of photographs is always owned by the photographer and no one else.

Say, if I'll take photo of Mona lisa, that photo is mine, but of course I can't reproduce it in full size and sell as the original. Simple as that.

Btw, in my opinion studying old designs is useful.

And I understand the situation with sponsors, but how far is wise to go?

To call a redrawn circuit by another name is not that clever. If Mike Matthews objected to his 30 year old circuits being published I'm sure that he would have said so
