Vero Layout: The Gristleizer

Here's a really ugly vero layout I did for the classic 'Gristleizer' circuit, the first circuit I ever took a probe to and figured out how it worked. I learned a lot from the circuit, as it provides elements of electronics present in both guitar effects and synthesizers.

It certainly hasn't aged well, the filtering is pretty terrible and some settings are borderline inaudible, with some knobs not doing anything in 70% of their settings, and using 5 LM741s seems ridiculous, so this one uses a TL074 and a TL072, with the voltage doubler hidden off-board (I had this in console style case that I never finished). A lot of fiddly parts chained together.

I've built several of these now and they've all come off really well. FuzzDog does a great PCB if you're in the UK too: https://shop.pedalparts.co.uk/Gristleizer_-_Mad_Modulations!/p847124_15740439.aspx

Anyway, the layout:

I told you it was ugly!

I often wondered why nobody had produced a vero layout for this, and then as soon as I put pen to paper, I realised why. Too many jumpers, too many cuts and too many specific parts needed to commit to making this unless you really want to.

The schematic I made this from was a beautifully neat Eagle schematic which now seems to have been expunged from the internet. I have a copy but shan't post it here as I cannot remember where it was from and wouldn't want to host it without asking permission first. But if you fancy it, have fun building this.

Self-verified, as I had this working for a while, and it sounded near identical to the three I bought from Fuzzdog.
