Boss FZ-2 Hyper Fuzz

Happy Fuzz Friday everyone! The Hyper Fuzz is Boss's take on the Univox Super Fuzz with a load of modifications. Schematic for reference here. Fits nicely in a 1590BB.

  2. Please can you show how you are numbering the lugs on the switch?

    1. Check out the General Layout Notes tab

    2. Oh and you'll need a type 2 switch btw

  5. Great layout, will build it soon but replacing the switch with a rotary

  6. Build the perf version and it works on first attempt. Just need to know how to correctly wire the 3x4 rotary switch as I got no clean boost but only the 2 fuzz.

    ReplyDelete

    1. Wire the common lug of your rotary to the Sw2 pad, then connect Sw4 pad to the first lug of the rotary for boost, Sw1 pad to the next lug for full, and Sw6 pad to the 3rd lug for scooped.

    2. Thanks for your help. You can mark it as verified.

  8. so i made it with catch 22! Used rotary swith, its easy. Took bc 549c. hfe 506 -513, you can mark verified!

  9. I had rotary switch for 4 points, so i add anonter mode from SW2 to collectors Q2,Q3 & get fourth sound bonus!

  11. Hey guy, can you make an layout version of this pedal? https://youtu.be/RqU0Gf0Thck if think this a classic jcm emulator layout... I need a verified version of this, can you help me? This is the best marshall in a box ever, with a great cranked sound. THX!

  12. Hey i am new to pedals and electronics, i just wanted to ask how do you know what voltage to use on capacitors from a schematic or a veroboard layout like this

    ReplyDelete
    Replies
    1. 16v or more, no matter what pedal or schematic?

      Delete
    2. For most pedals that run on 9v power... yes, that would be OK.
      If you built a pedal that could also take 18v, you need to use capacitors that are rated HIGHER than the voltages running in the circuit. Make sense? That way your caps don't get damaged by taking more power than they can handle.
      You really need to check what kind of circuit you are building and then choose the parts that are good for that pedal.

      I highly recommend that you check out some of the "beginner" resources that are available on other sites. They will probably help answer many of those newbie questions. Here are a few good ones:

      I could keep going, but some Google searches will get you more links and sites to get you going.

      I hope that helps. Good luck!

    3. Oh... one last idea.

      This is probably not a good pedal to start with. David's layouts are way easier to deal with than many out there, but still... this is not exactly a simple build. A Fuzz Face or the Acapulco Gold posted in the Coda-Effects page would be a better starting point.

  13. Can I use bc550 instead? And I have a couple of toggle switches here from tayda, but from their site it says on/off/on can I use this?

    ReplyDelete
    Replies
    1. BC550C would probably be fine. But on on/off/on is gonna be a kill switch in the middle position.

      Delete
    2. bc550 - exellent choice! Use better rotary switch instead on/on/on. like this https://www.alibaba.com/product-detail/2-12-Position-Rotary-Switch-With_60248654566.html?spm=a2700.7735675.normalList.109.6fb3f936SpUOjH&s=p&fullFirstScreen=true

  14. I Must try this layout ?? hi friend .. one request can you make a layout jhs andy timmon i searched on this site but no 🙏 sorry for my english 🙏

    ReplyDelete
  15. Hi David! So far, seems like those who have verified this have used rotary switches.

    I'm putting this together with the DPDT on-on-on switch and I think the last thing that's needed is jumper lugs 3 and 5 together (to connect the two sides of the switch). Otherwise the switch wiring numbers are good per your layout diagram.

  16. F*ck yeah! D O P E T H R O N E

  17. I using on/on/on dpdt, i thing sw4 must be sw5... Is that correct ?

  18. trying to scrounge for parts..looking for a good sub for this diode?(D3 1N5817) would 1n5818 work? thanx

    ReplyDelete
    Replies
    1. Yes, the 5818 should be fine. I think the only difference between the 5817 and 5818 is the voltage rating.

  21. The 10k from pin7 of left TL072 is bypassed. And the 33nf is misplaced.

    1. Just cut the trace after 47pf from pin 7 of TL072 and its works awesome.

    4. Thanks Marcello, that helped a lot, but I'm still not getting a very good quality fuzz out of this circuit. Can you post your voltages for Q1-4? The way my circuit is sounding I think something isn't biased correctly.

  23. Hello everyone! I have two question:

    1) Is there a way that I can you a dpdt on/on switch to toggle between fuzz 1 and fuzz 2 mode?

    I can't find a on/on/on switch in my country and i can't buy online because is a pain in the ass. Also, i really don't care about the boost mode.

    2) Is it ok if i don't add the 5817 diode? I have a 9v negative power supply, so there's no way I can plug another power adapter. Or is the diode important that also works on the power supply for the pedal?

    Thank you!

    Juan.

  24. Good articles for question 2 not sure about question 1

  25. hey on the switch question...why don't you just try it and see what happens? just solder wires to circuit board then use a breadboard to test various switches you have laying around. also dont forget to cut the trace after 47pf from pin 7 of TL072 as described above. also some builders use a rotary switch instead of a toggle switch..rock on bro!

    1. Wait... what?! I have to cut what? Why? :o

      I have to cut the trace between pin7 and 47pf? Sorry i didn't understand well :/

    2. I dont understand too, my fuzz dont work... :/ I wanna try to debug this... I should be start with this cut?

      Delete
    3. no, this cut isn't the issue if it doesn't work at all.

  26. someone has a diagram of the installation of these DPDP, I'm a little confused, because a position of the switch is not working.

    1. Precisely, this was the connection made by me, but the position 1 and 2 of the switch sounds exactly the same.
      hence the question.

  28. you'll need a type 2 switch btw

  30. Hello, it is not the Boss Hyper fuzz fz2, this circuit is different (Hyped fuzz), it would be very good to do the original. Thank you. Sorry for my English.

  31. This is awesome. Thank you so much for this layout. This is the first board I’ve ever etched and I love this pedal, everything works!
