Biyang Tonefancier Blue BL-8 [schematic]
I really like this pedal. I’ll work on a schematic in a bit but here’s pics for now. I’m wondering what it’s derived from.
It’s very warm (no treble), has loose bottom, very smooth, a ton of output. Only thing I could see wrong with it was some nuts were loose.

Did you manage to work the schem out!? it seems a little but funny circuit...curious to read it!

It looks like a proco rat without the output buffer and leds instead a diodes, it's easy to implement a tone control.

I was about to say yeah, it looks like a RAT.

I made this PCB clone for tracing, can you please put the component values in the picture with the components.

Right! Just got one today for cheap, man let me say it's one of the worst pedal I've ever played! it can get some use with just a zic of gain, turn it up and you get lifeless mud sound...

This pedal is similar to the FAME Slasher DS-10, so I just had to edit its schematic.

Can you please measure the values of the potentiometers and the resistors?

gain is b100k and volume is b10k

Thanks, are the resistance values correct, have you already checked them?

Yes I did, you wrote in the previous post:
Therefore I wrote:Got a problem with 1/8 metal resistors, quite difficult to read for me, guess it will be easy for others to complete the schem.
I think we are talking at cross purposes, did you measure values of resistors to confirm them?Can you please measure the values of the potentiometers and the resistors?

Right, I wouldn't read those damn resistors, I just measured with MM.
The previous image I uploaded has been updated.
Guess I'll transform it into a grey dod 250, it should be quite easy.

Here the verified layout and the verified circuit diagram.

Super easy to add a tone control to that and make it into an overdrive with a couple 100k pots.

small correction on the schem, gain is 100k linear not log. please change accordingly.

The potentiometer type I have changed circuit diagram above.Renegadrian wrote: ↑01 Jan 2021, 01:26 small correction on the schem, gain is 100k linear not log. please change accordingly.

Love this pedal -- huge thick tone with good sustain. Great with single coils.
