PedalPCB Hyped Fuzz

Two layouts of this one. One with DPDT on/on/on selector switch and one with rotary switch.
Rotary switch layout is verified.

  1. I see new tag for Verified and Unverified layouts. Cool thing!
    Is this really Verified? I thought it wasn't early.
    Thanks.

    1. I built the rotary version a couple days ago and it works. Instant Electric Wizard tones. Didn't had any on/on/on switches on hand so...

      Yep, all layouts has Verified/unverified tags by now.

    2. Great! It's on my top heavy Fuzz wishlist since some years. Proabably I'll build it next years! :D

      Thank yuo very much, good idea those tags.
      I scrolled it quickly. Just pay attention: some layouts has "Unverified" in the description/text, but is tagged Verified.

    1. I should have written in the notes that the switch is a Type 2 switch.

  5. Thanks for the layout! Built this using a type 1 dpdt and adapting the wiring. Sounds almost identical to my SF300, except this one hisses like a mofo on both Fuzz modes, but it is extremely quiet on Boost... Troubleshooting here we go :)

    1. Well, it wasn't that hard actually... For Q2 and Q3 I had apparently installed a BC548C and BC546C.
      Ended up replacing all of the transistors with lower gain 2n3904 (not matched or anything but at least from same batch), and added a 100Ohm resistor between +9V and the board just for safety.
      I plugged it in and now it's perfectly quiet and peaceful, as every Hyperfuzz should be :)
      In the end I did not figure out if the problem was solved by matching Q2/Q3, overall use of lower gain transistors or the added resistor, but I don't really care

    2. Excellent, glad you got it solved. Yes, stock Hyper Fuzz had really low gain transistors, I have no idea why PedalPCB specifies this one for BC549C?
      "Quiet and peaceful" Ha!
