Welcome. I wanted to provide stripboard layouts I've made to help people new to electronics and even the more experienced get into different aspects of electronics.

I verify the layouts before I post them.

Boss OD1 14 Pin Version Stripboard Veroboard


a guitar overdrive, quite a nice one - it uses a quad op-amp this buffers the input and output signal before/after it's passed through the overdrive which makes your guitar quite responsive but not with over the top overdrive.

this is one someone asked me to make for them - they wanted the "14 pin version" and not the "8 Pin version" basically Boss decided to reissue this pedal without the buffer parts - most probably because the op-amp they used had a none standard pinout to a jellybean one like a LM324 and instead of redesigning the board to use a different quad they redesigned the board to use a dual op-amp, I'm not entirely sure what the thinking was there but here is my version which is a quad op-amp version to use a normal quad op-amp.

    Maybe a dumb question but can you use the RC3403D with this layout? Is there a schematic that you used for this layout available? Also, could you show the pot wiring?


    Cheers

      when I did this - I just found the schematic on google - it was quite some time before I did this blog so I haven't got a clue where it is now.
      I can't absolutely confirm that you can use the RC3403 because the only one I had was a pre-used and highly abused one and it didn't sound right but when I put the equivalents in it - it worked well so I imagine you can use the RC3403 but it won't sound any different it will just cost more.

      with the pots the 1M/10K refers to the pot value in ohms and the number after those are the lugs they are wired to -

      eg "1M 1-2" is a 1 megohm pot with the board wired to lugs 1 and 2 on the pot

    Hi, I'm wanting to build this pedal but increase the amount of gain available. Which component is responsible for the max gain? Thanks so much for the layout by the way!

      I did this one so long a go (that's why the layout is very spacious) I can't remember much but if my memory serves - if you increase R5 you should get more gain
