Morecowbell, thanks for those great links you posted, but if they are all avaible from one location, it's better to just post that one link. If people are interested in discussion about this or that box, that can become a separate thread.

They are all in the $59-159 price range! Anybody has more info on this brand, we're still waiting for the english version of the website..

Since I retired in early July last year, I've been digging around the 'net, trying to find schematics (circuit diagrams if you're a Brit!) for guitar effect units (Phaser, Wah-wah, Sustain, etc.) and I've come across some beauties! I apologise in advance if they've already been mentioned elsewhere on this forum - I have had a look, but you can only go so far back!

Firstly, I found It's a site that collects English-speaking publications from around the world - Britain, USA, Canada, Australia,...

A very nice guy called Joe Palermo was going through some stuff and found this. He decided to donate the high quality pictures he took to a facebook group. I downloaded the pics and compiled it into an indexed PDF.

Here is a handy, perfectly readable lores version of this file. I need so sort some serverstuff out, then I will be able to host the higher quality versions I have. Done.
