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.

Amptweaker Defizzerator Stripboard Layout

I went to the shop yesterday hoping to buy 2 Amptweaker Defizzerators for a recording session but of course; they only had 1, so I bought 1 and reverse engineered it. it's a passive circuit so you get a bit of loss and I may work on a buffered version at a later date but for now;

My bands albums;
Double Negative - The Day The Dark Won
Double Negative - When We're Gone
Digital Versions


  1. Hello, Paul. Great work. I have a question regarding this schematic. The way I see it, with the switch in the middle position, the pot have no effect. Shouldn't C1 be connected to SW2 instead of GND?

    1. this is how it was on the original, the "fizz" option is the highest range so it's fully on because it's not too noticeable anyway, the other 2 options are where you need the control. either way, both of the boxes sound the same.
      it was quite a nightmare to trace out cause the switch they use is some weird selector.

    2. Ok. Thank you for the verification. Keep up the awesome work and all the success for your band.
