Wampler Sovereign

The Wampler Sovereign Distortion is a versatile beast of a distortion pedal that is unlike the rest of its ilk. The gain is rich and full of harmonic overtones, never sounding or feeling fake and stiff. Surprisingly shapeable and responsive, the non-traditional gain and EQ controls allow you to tune the pedal to suit any setup, and instead of just emphasizing a certain frequency range, they actually change the texture of the gain. With the right settings dialed up, it can nail the elusive sludgy deep sound loved by stoner metal guitarists, along with virtually every other shade of high-gain tone a player can imagine.

    2. Thanks Alex!

      Both ends of the 10k connected to Tone 1 should be moved down a row.

      Also, if polarity protection is desired, move the 47k (near the mids) left 1 column, raise the bottom of 10R up 2 rows and move the 10R right 1 column, add cut to the right of Q4-G and add a 1n5817 to the left of the newly placed 10R, between bottom of 10R and the link 2 rows down.

    3. Thanks Michael!
      Must have moved it by mistake.
      I've also added a polarity protection but in a different way

  4. For the 100k trimmer what would I have to set it to. This seems like a very interesting project.

    1. It acts as the drain resistor for the last jfet stage. I would set it by ear.

  6. I just built this. Tried a few different ICs and settled on JRC4558 because I didn't have a 4580D. Oh man it sounds awesome, always have been interested in this pedal but not sure if I wanted to buy it. This one is going on the pedal board for sure! Exactly the sound I've been looking for. I see its still unverified, you can mark it as verified and mark it as awesome.

      Looks very similar to a Pinnacle. Were there any squealing issues at higher gain/boost settings that would warrant shielded input cabling like we had to do on the Pinnacle?

    2. I was surprised how quiet the pedal was even with the gain maxed out. I didn't use any shielded cables and personally didn't have any issues in my build.

  9. This pedal rocks. Sounded best to me when drain on J201 underneath trimmer was set to 4.5v. Definitely one for the pedal board. Thanks as always Alex for the layout.

  10. Hi guys, I need your help. I would like to build this pedal, but I don't have any j201, Is the 2N5458 a good replacement for this aplication? Thanks in advance.

    ReplyDelete
  11. My understanding and in my experience you can totally sub 2n5458 for a j201. It would sound different though.
