If you'd like to, sure that would be great.

What would be most help is a semi-physical drawing. I have better versions of the schematic and parts placement pages that were listed. If you could take the parts placement drawing of the boards, and sketch out which wire goes to which jack/switch lug/other board that would be a huge help.

Drop me a pm with your email address.

hey rg

i sent you a PM.

looking forward to having a crack at it

Wow, It could be a nice challenge to build one of those . Hey, am I the only one who likes wiring? I love building too, but wiring is almost the end, that's why I like it. Hopefully I'm also very patient and check everything more than once(maybe that's why up to now all my builds ran at once).

Still I don't know exactly what it sounds like, gotta check some sound samples on the web.

EDIT: Haven't found any, any idea were I could get some sound samples of this?

Sonic Youth used it a lot on their album Washing Machine, the Diamond Seas has it.  It is a fuzz and filter and tremolo all in one.  Two filters that can sweep up or down, or opposite each other.

[R.G.]

By the way Chris, Ulysses is going to try to nail down the wiring so it can be reduced to practice. Do you have or can you make a similarly revealing shot of the console board so he can trace the board-to-board wiring?

[Sir H C]

I can send him a bunch and I have some better pics of the two schematics.

What was wrong with this one:

(there is a rivet bit jammed in the switch in the center of the shot)

Hey, thanks. That may be enough to track the rest down.

As for what it sounds like, those of you who don't have Sonic Youth's Washing Machine, the effect that is on "The Diamond Sea" is kind of like a phasor with a much more vowelly sound, so instead of "woooosheeeeooouuuwooosh...." it's more of a "yuheeyuheeyuh" effect. I have been able to get approximations with plug-ins, most recently BU Guitar Rig II, which has a "Talk Filter" effect that can be controlled by a virtual LFO module.

If there was a pedal that did just the formant filter phasor effect, that would be awesome.

I can't say what the fuzz or other settings of the animation sound like. I'm really just going off of hearing the Beck and Sonic Youth songs which use it.

After some digging, I found the drawings of the offboard wiring that a generous person over at ampage made for me years ago.  I don't have access to a scanner this weekend, but I will get it digitized and to you guys early next week.

KEWL!!! Send them on!

2 Constant Q Filters;

left halve of each filter = variable capacitance,
right halve = variable inductance sim,
both variables synced per filter.

R.G.: check yer PMs 

[R.G.]

I'll go have a look.

[King Tubby]

There's one on ebay... but this time without the huge starting price!

might be worth a punt.

Cool

This is the first time I see someone next to it; I though it was much much bigger

[Isaiah]

Ooh, this looks interesting.
Is anyone drawing up a schematic of one of the filters, please?

[Isaiah]

Those interwebz are really working fast these days,
from the bottom
to the top...

Yep, have those. They're part of the stuff that went into the schematics that have been on GEO
since March of 2004.

Any new findings?

Just like this fig.6 explains, so you guys in the other thread know what you`re doing!
