No problem at all TMZ, thanks for sharing! We do have a lot of Japanese members, but there is still a language barrier.

I think a lot of people here would like know more about the Japanese DIY pedal world.

This is a layout from ROX OF BOCK schematic that I made with KiCAD:

    C12 10uf

    Pots:
    RV1 C5K (GAIN)
    RV2 B100K (TONE)
    RV3 B100K (VOLUME)
    RV4 C5K (BOOST)

    Semiconductors:
    D1 Zener 9,1V
    D2 Zener 9,1V
    D3 Zener 9,1V
    Q1 BS170
    Q2 BS170

Very nice layout thanks. I wasn't aware of that Kicad program it looks interesting.

Quick question, is that boost section a seperate piece or is it just show seperately here as an example?

Also, Is 'Gain 3' connection marked twice and where is the output from? Vol 2 connection?

Many Thanks,

I want to make a box of rock standalone distortion side only, I dont want the boost section. Anyone have a vero layout of this? Or can explain how I would go about this?

I'll plug my layout too, since it's the only PCB I've designed :oops:

hey mark your layout looks tight. nice work. It looks like you did what I was looking for, you left out the extra sho and boost section. Nice, I might have to learn how to etch now. :)

I don't see the similarity between the BOR and the BSIAB. :? The more I look at the SHO the more convinced I am that the idea came from a big muff stage. And the suggestive name :wink: Mosfets bias up very similar to a bipolar transistor. The BOR looks more like a mosfet big muff without the diodes.

The comparison comes from the fact that the BOR uses a Big Muff tone stack with the BSIAB2 values.

I've heard that before too, and based on that alone IMO the claim that the BOR is a "BSIAB2 clone" is tenuous. My guess is Zvex saw how popular all the "amp sim" jfet circuits were and decided to take a stab at that approach with his beloved MOSFET.
