Colorsound Wah Schematic

Exactopposite · February 17, 2004, 09:45:53 PM

first off, this is my first post here. i'm glad i found this place. i went college for electronics and i had been wanting to start building and modding eefcts but i didn't know where to start. looks like there is a wealth of knowledge on here.

I have a colorsound wah reissue that i really love. i don't want to mod it , but i do want the schematic in case something happens to it. the only colorsound wah schematic i have is from a wah/fuzz pedal but it's not the same as the one i have. (it's a different drawing but the same as the scematic at fuzz central)

i do want to use the schematic i have to build another one to experiment with and compare to mine.

can anybody help me with this?

I believe there are different versions for thsi thing. I own an original one, which is *very* close to a Vox.
If noone comes up with a schem I could open it up - it's not a difficult schematic at all.

yeah there aren't very many components in it at all. as far as building one for myself i have a schematic but it's not the same as the uni that i have. there were colorsound wah's with and without inductors. mine has no inductors but the schematic i have does.

which flavor is yours?

I have the inductor one, like I said it's almost a Vox. Couple of different parts, more dramatic sound.
A No-Inductor wah will probably be some kind of twin-T circuit.
You could try to take digital pics from top and bottom of the pcb - it's pretty easy to construct a schem from that.

hey that's a great idea. i never really thought of that. i'm getting a strat 2moro and i can't wait to see what the wah sounds like with it. i have been using it with humbuckers for a long time but if wah is your thing, there is nothing like single coils and a wah.

I suspect their old pedals are not a million miles from equivalent EH pedals. I remember opening up a Jet Phaser when trying one way back and it used 3094 chips.

Not too unlikely (JumboTB vs BigMuff, or a SupaTB....) - but did EH have an inductorless wah? Maybe Maestro, or other contemporaries.
I wouldn't be surprised if we could rather quickly set up a schem from the two pics - let's see...

There was a schematic on the web in the past. IIRC it is a twin tee design.
