Cruising the internet I came across an interesting web site with a shit load of service/repair notes on a shit load of their pedals along with schematics and board layouts.
Maybe most of you have been to it but for the one guy who's looking look no further than
here

I only briefly looked over one of them so I'm not sure how informative they are.
I mention there's a shitload of 'em?
 
AWESOME find! Thanks!
I've rev-engineered several from these over the years using the service manual PCB layouts - most recently the MIJ Boss DS-1.

FYI - the DS-1A service manual has a cleaner version of the MIJ DS-1 schematic, as well as the original MIJ layout.
Another FYI - if you're able to work out the HF-2 Hi-Band Flanger layout, you can (theoretically) use that to build a BF-2 as well. Different part values in some places, but the architecture is pretty much the same.

These are awesome resources. Thanks for sharing. Sadly, the one I need is not included. Anyone know where I can lay my hands on a Boss CE-20 service manual... and/or schematics? I have one that's just started to give no output when switched on. Bypass works fine, but nothing when chorus is enabled. Also the two blue rate lights seem to be permanently on instead of pulsing at the rate speed. Any advice welcomed.

Man. That's all digital...
Try the test mode of the other 20 series. Page 13
Maybe the same info applies here
 
Perfect. Thanks jwin615. Will check this all out and let you know how it goes. Certainly the power supply elements are almost identical. Thanks. Also, I hadn’t realised that there was a reset process. Will give that a go too.
 
This site unfortunately isn't free like the others, but on a few occasions they've had factory service manuals I couldn't find anywhere else.

They do sell some questionable items like owners manuals and instruction booklets that you can easily find online for free, but there are a few obscure gems in there that I haven't been able to find anywhere else.

This is where the original Boss FZ-2 service manual came from when designing the Hyped Fuzz, at that point there were no other verified (or correct) schematics available.

WOW! Robert that is a massive accumulation of manuals. Very cool thanks for the share. It is too bad that they have to charge for things like this when most CAN be found free on the web. Is what it is though.
Does anyone know of a site having DOD owners and/or service manuals?

Some of the ICs are no longer available (eg CA3046), and some of the ICs that Moog have used are a bit questionable (eg charge pump IC frequency is in the audible range) so I’m just wondering how good their actual engineering actually is…
