EarthQuaker Devices Spires Green Channel

 A Rosac Nu Fuzz done EQD style... Heavily modified values compared to the stock Rosac schematic that is floating around online. It suggest that it should have more volume on tap and a tone control with much wider range than its ancestor.

Schematic is avaiable HERE.

  1. Excellent, thanks mate. I dont suppose you could have a quick look at the flanger layout, its hurting my brain checking it over. Thanks again mate

    1. I have checked the Pearl Flanger severeal times without finding any issues. Madbean just released the Kingmaker project which is based on the FG-01. That schemaic is easier to read but keep in mind that there are some mods added; a bias trimpot and alternate connections and resistor values at the MN3207 chip.

      Pearl factory schematics are usually reliable but some of have some minor bugs, hopefully this isn't one of them...

  2. Yes, the one closest to the top is Level 1. Volume 1 almost always is connected to ground.

  3. Just built this one and it works great.

    It gets loud!!

    I did get the level wires the wrong way around, but once I swapped them, it all works great.

    Sounds good. May not be going in a box as it's not quite to my tastes, but the circuit works fine 😁

      'Tagged and the Level 1 label is corrected.

  4. Works great here. Boxed it up! Happy that I got to use some of my surplus of 2N4401 transistors.
