Univox super-fuzz (orange model)

I'm looking to make a univox super-fuzz (orange version). I am looking for a layout of this model. Does anyone know where I can find what i need to make this? Thanks

So many options... here, here, here, or I know our own Mike has made a perf layout that gets mad props from the DIY community, or there's the BYOC Leeds fuzz nowadays, which is great (I've got one).

Do you want to make a stripboard version? If so, here is the fruit of my labour:

Note I use the original transistors. These have an odd pinout, this layout will not work for more modern replacements with a CBE pinout.

yeah a stripboard layout is what I was looking for. Thanks Mike.

This is the model that I'm going after. I think the layout is the same as other models but with different transistors.

Those transistors have the same ECB pinout as the 2SC828 and so are fine to be subbed into my layout. Have fun!

That site is where I got the schem that I sent to Mike in the first place from - it's changed a bit since, but same site.

someone posted this over on DIY stompboxes. appears to have a different number of resistors and caps. plus a trim pot.

Mike what did you base your layout on?

The original Univox Schematic I believe. There were variants I'm sure.

That one does not use the transistor pinout you are intending to use, it's for more modern CBE pinouts.

Ok thanks mike.
