I've never even even heard of this. There's a component side shot in the auction.

Reading between the lines it doesn't sound so great so maybe that's why they didn't make so many. But I think 79 must have been near the end for Colorsound anyway?

I'm pretty sure that's been re-listed a few times: I recognise it because the same guy has also re-listed this weird Orange/Gary Hurst Tremelo prototype a couple of times:

Maybe there are some obsessive collectors out there who will pay that much for these oddities, but it seems not that many.

If you're using Firefox, click "enlarge", right-click outside the image area but inside the pop-up window, select "view page info", go to the MEDIA tab, and select/save the pic.

I know he bought it very cheap last year, around 200 euro or less in a BIN auction (I was a little too late...).

You need an older browser.... I am using IE 5.5 and don´t have any problems saving pictures.

No individuals please. 1-Source is a business-to-business distributor.
Minimum order $250.


I have the same problem with SAD1024 chips, several broken pedals which probably need a new chip: EH Full Double Tracking, EH Slapback Echo, Monacor (Univox) Flanger/Delay,...

Someone makes an adaptor PCB to allow a MN3007 to replace the SAD1024. My Google-fu is weak today, so you'll have to look for it yourself! :)

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

Couple of the component side.

Regarding sound... it's nice enough for what it is but the wet level is quite low, max delay clock setting was 3.8kHz (I think, going from memory a bit) so about 135mS max delay and it is murky.

The 2 trims next to the SADs are clock cancel and the 2 further away are the bias, the 741 is the voltage regulation circuit and the TL061 is the clock.
