Third Man Records Bumble Buzz

From the Source:

The Bumble Buzz Pedal, HAND MADE by Chris Young of Union Tube & Transistor (who built the pedal used for Jack White's guitar sounds on "Sixteen Saltines" and the vocals on "I'm Shakin'" off of 2012's Blunderbuss), is ready for buzzing around and stinging sounds. Designed by Third Man Creative Hive.

Input impedance: Zin @ 1KHz 30K / Output impedance: Zout @ 1KHz: 33K.

Essentially it's just a modified Kay F1 Fuzztone, which itself was just a simplified Univox Super Fuzz.

  1. Nice one ! It was on my to-build list for a while now. I guess I have no reason not to try it now !! Thanks !

  2. I made one a while back using the layout link below. It’s a one trick pony, but It’s damn fine at that. https://vero-p2p.blogspot.com/2020/07/union-valve-transistor-bumble-buzz.html?m=1

  3. Are you sure about the 330K on the Output. It looks that it has to go to ground.

    1. good catch. i forgot to resave the layout after moving stuff around. should be correct one now.

    2. Now the Output is on the wrong side of the 1nf Cap?!

    3. ...and the 330k is on the wrong side too.

    4. check it again. it shows up right for me

    5. Looks good to me. Thx Zach.

    6. Shouldn't the negative end of the 10u input cap go toward the Base of Q1 rather than the 22k resistor? Or is it just acting as a regular cap and the polarity doesn't matter?

    7. I build it like this and it works.

  4. Hey, Zach. Doesnt this have any knobs at all? Like the EQD Tentacle?

    ReplyDelete
  5. It might be cool to combine them into a pedal with two footswitches and no knobs haha. I would do it but I've already built myself a Tentacle clone

    1. sorry I meant to reply to Edweirdo's comment oops

  6. I built a version of this a few months ago. It works so well as an on/off octave fuzz that I pulled the tentacle from my Hoof Reaper and replaced it with this.

  8. What common diodes could be substituted on this? I dont seem to have 4007s.
    I have most of the usuals.

    1. any 1n400x will do.

      they only differ in peak inverse voltage. when it comes to clipping they should sound identical

  9. You can call this one verified! Sound great with PN2222s. I may add a volume pot but its n absolute fuzz monster.

    1. I build it today. What kind of Pickups do you you use? I use 8k to 16k Humbuckers straight in the pedals and get fuzzy sounds only when playing chords - singlenote lines came out almost clean. The octave is there but not heavy(like on a superfuzz). I checked my build multiple times but the gain is to low for some reason( i use metalcan 2n2222as).

      Delete
    2. I build it too, no fuzz at all. Checked it a million times, all parts are there, all soldering is o.k. Do I need a groundwire from my jack in/output to row N ? What other problems can I look at? I use 2n2222a . Tried both metalcan/pnp. Nothing happens.

      Delete
    3. I play a J Mascis Squire Jazzmaster. I believe the pick ups are a p90 variant. Jacks and foot switch should both have ground connections. What I ended up with sounded exactly like the demos.

      Delete
    4. One step further, now I only hear motorboating. I think I will change all the capacitors. perhaps that might help?

      Delete
    5. Mine works now. I had a connection between two rows which doesnt belong there.

    7. If I end up with a faulty build (on a verified layout) I will usually try to trouble shoot a bit. I will proof read the cuts, links, component placement and look for solder bridges. I may try measuring values of what is on the board but I have to start swapping components without knowing they are the culprit, I generally start over. I figure if the mistake is that hard to find Chances of replicating it are slim. I also stock my parts well beyond my immediate needs so it’s no trouble to toss a failed build in the can. I usually end up good after that, especially because I’m slowing down and being much more meticulous. This logic isn’t always sound. I recently built a Sweet Honey for a friend and volume didn’t work. Tried a new pot, didn’t work stared at it, measured both non working pots and everything looked great. It just didn’t affect the sound. I rebuilt the entire thing and had the same issue. Turns out I forgot to attach the ground to one of the lugs. Similar situation with a Megalith for the same friend. Bad boost pot. Just wasn’t acting right and I’ve built a few of these. Everything seemed fine but as I got ready to rebuild I finally realized the value of the pot was 5times what it should have been. I am prone to doing dumb stuff.

  10. Also, I used 1N4001s in place of the the 1N4007s. It does sound exactly like the demo. Another plus is that when not playing it is dead quiet.

  11. what is the use of the cut under the 100k resistor next to D2 (right) ?

    1. nothing it's left over from moving parts around

  12. Build this one and it fired right up with no issues. I used pn2222’s, and on my transistors the pinout was opposite of the layout, So be sure to double check the pin out if you’re having issues and everything else seems okay.

  13. Built this and compared it to my housemates real one that arrived yesterday, sounds pretty much identical. I added a 250k Vol knob at the output because it's pretty unusable without it. Used 2n2222, 1N4002 diodes and put a switch to add a 2.2n in parallel with the other 2.2n to double the LPF cap to 4.4n as it is severely shrill. Definitely more of a play with the band than a play by yourself pedal. Much more versatile now. I had been toying with buying one until I saw the price $325-660 used. Excellent timing for the post.

  14. Finished building this today (kinda). First I tried to solder one together last night (and it didn't work), so I put it together on two small breadboards. It took a bit of troubleshooting, but I finally got it to work today. ---Question: Is it supposed to have both the LOWER and the UPPER octaves as well as the guitar? (I only hear the upper octave and the guitar) Perhaps I wired one of the electrolytic caps wrong (polarity) - I only have electrolytic caps for the "uF" caps. FYI: Transistors I used are 2n2222 NPN

    1. Interesting - definitely no sub octave on the one I built.

    3. I was about to build that one next to see if it had the lower sub octave. So.... it doesn't? How can we add that? (I'm a n00b) - BTW, I appreciate all of these vero builds! (Andy & Zack, and anyone else who posts these builds)

    4. I'd love to know how to add a sub octave to this AC - that would be a monster fuzz - what did you do??? I can't hear any sub-octave or see it on the scope. Maybe the prominence of the octave up made it sound like there's a sub octave???? This is my build on the scope - no visible sub-octave. Very prominent octave up. https://1.bp.blogspot.com/-oQq6LxO5H6o/XxI2m_hkFVI/AAAAAAAAFfY/Y-KdN8UzvBsMwX-E3EPdn5RsEVLA8mP2ACLcBGAsYHQ/s1413/Bumblee%2Bbuzz.png

    5. oh and i should have mentioned that the source signal is 440hz. The octave is so prominent my scope listed the second harmonic as the fundamental.

    Thank you. I've been saving this for a low/zero pot build.

  16. Is there a reason why I wouldnt be getting the octave up? I’ve triple checked all cuts and tracks. It’s sounds good but no octave just fuzz. I’m using 2n2222. Two metal two plastic. Thanks.

    1. Did you doublecheck your transistor pinouts? My plastic ATP2222A's that I got from small bear were reverse of what's shown on the layout.

  17. sounds awesome! I removed the 330k resistor and did a volume pot (tried a500k and a250k and both seemed the same) because this thing is REALLY loud.
