It’s Raining Germanium!

I just bought 500 germanium transistors. Yes, as a matter of fact, I am insane. Why do you ask?

UPDATE: My Dunlop Fuzz Face Mini review is live at Premier Guitar. Audio clips included!

How and when did it get so frickin’ easy to procure great-sounding germanium transistors?

I’ve been building stompboxes for four years or so. I used to consume article after article detailing the sheer horror of dealing with germanium. Sure, those old-school transistors sound great, I’d read, and they’re necessary for vintage distortion circuits. But they’re unstable. They’re expensive. They’re hard to find. You have to sort through dozens to find the few good ones. And once you do, you must spend countless hours matching and biasing them for optimal sound.

I believed everything I read — until I finally admitted to myself that I seldom encountered any of those problems.

(If you don’t know much about germanium transistors and why they’re cool, here’s my manifesto.)

I used to buy germanium transistors from Small Bear and other parts sites, and was always happy with the results, even though I had to pay eight or ten bucks per transistor. (Small Bear even does the matching for you, offering sets of transistors suitable for various vintage fuzz circuits.) However, it was a little tough finding NPN (negative-ground) germanium transistors. In fact, Small Bear once rejected my order of a dozen or so NPNs because they were so scarce. (To his credit, Small Bear’s Steve Daniels explained that he restricted sales so that everyone who wanted to build a couple of great DIY fuzzes would have the opportunity.)

The workaround is to build pesky positive-ground pedals, or jigger with the schematic in order to use PNP (positive-ground) transistors in negative-ground circuits. (This site’s Fiendmaster project is an example of the latter workaround.)

Then some odd things happened:

Fuzz Detective:
The Case of the 12 Germanium Fuzzes

As threatened, the Fuzz Detective video:

WHAT: Twelve germanium fuzz circuits compared and analyzed. These represent the sounds of almost every fuzz pedal introduced between 1962 and 1968.

WHY: A tool to help players identify the circuits most relevant to their musical needs. This isn’t about particular brands of pedals, but the circuits they employ. If you hear something you like, you can either do as I did and build a clone from the schematic, or buy one based on that particular design. (The relative merits of rival clones is another story.) Of course, if you’re rich and you desire an ancient pedal that probably doesn’t sound as good as a new clone, you can always purchase a vintage original. 😉

HOW: I tried to establish a “level playing field” by removing as many sonic variables as possible. I used the same signal chain, the same guitars, the same musical material, etc. (Tech details below.)

WHO:

  1. Maestro FZ-1 Fuzz Tone
  2. Sola Tone Bender Mk 1
  3. Hornby-Skewes Zonk Machine
  4. Sola Tone Bender “Mk 1.5” (similar to Vox Tone Benders)
  5. Dallas-Arbiter Fuzz Face
  6. WEM Pep Box Rush
  7. Sola Tone Bender Mk II (same as Marshall Supafuzz)
  8. Mosrite Fuzzrite (germanium version)
  9. Orpheum Fuzz (germanium version)
  10. Selmer Buzz Tone
  11. Sola Tone Bender Mk III (same as Park Fuzz Sound, Carlsbro Fuzz)
  12. Baldwin-Burns Buzzaround.

WHEN: Like, now, man!

Fuzz Detective: The Plot Thickens!

Man, I’m glad I announced my intentions about this project! Thanks to your links and suggestions, the “Fuzz Detective” project has grown vastly more ambitious. I need a few more days to make my test recordings are assemble the results, but I believe this will be the most complete and “scientific” audio comparison of 1960s fuzz circuits yet attempted. I’m posting this update to share my current plans — and solicit last-minute suggestions for improving them. —Joe

Wanker's Dozen: twelve Germanium fuzz pedals compete on a level playing field.
Wanker’s dozen: twelve germanium fuzz pedals will finally compete on a level playing field.

I’ve been a busy little solder monkey! Dig my new pedals:

1. Maestro Fuzz Tone FZ-1 clone
2. Sola Tone Bender “Mk I” clone
3. Sola Tone Bender “Mk 1.5” clone (near-twins: Vox Distortion Booster, Italian Vox Tone Benders)
4. Dallas-Arbiter Fuzz Face clone (very similar to Tone Bender Mk 1.5)
5. Hornby-Skewes Zonk Machine clone (near-twin: Tone Bender Mk 1)
6. Sola Tone Bender “Mk II” clone (near-twin: Marshall Supafuzz)
7. Orpheum Fuzz clone
8. WEM Pep Box Rush clone
9. Mosrite Fuzzrite clone (germanium version)
10. Selmer Buzz-Tone clone
11. Sola Tone Bender Mk III (“3-knob”) clone
12. Baldwin-Burns Buzzaround clone

About the Fuzz Detective project:

I’m attempting to create a comprehensive comparative sound library of germanium-transistor fuzz pedal circuits.

There’s no shortage of audio clips and demo videos featuring the great stompboxes of the ’60s and their modern clones. Yet it’s difficult to make qualitative comparisons between circuits because there are so many other variables at play. Who performed the examples? Using what gear? Were the examples recorded in a pro studio or on a mobile phone? Are the pedals ’60s originals or modern clones? What’s the condition of the transistors? And so on.

This isn’t about, say, deciding who makes the best Fuzz Face clone. The focus is the circuits themselves. The Fuzz Detective project aims to “level the playing field” by removing as many variables as possible.

Next Week on Fuzz Detective!

UPDATE: Based on cool info supplied by YOU, dear readers, I’m expanding the scope of this piece. I’m furiously wiring up clones of some very rare models, and I can promise many cool and interesting surprises. Thanks, guys! :beer:

Okay, now that we’ve all gotten that silly “reading” stuff out of our systems with Book Week, it’s time to get back to the real focus of this blog: nasty, filthy fuzz pedals.

Last time we were on the subject, we looked at the original version of Dallas-Arbiter Fuzz Face, and included Mitchell “super-freq” Hudson’s beautiful DIY instructions.

Those posts generated many interesting comments — plus some misinformation on my part. For example, I said that the original Fuzz Face circuit is a close cousin to the Tone Bender Mk I, which would mean, for example, that known Mk 1 user Mick Ronson was essentially using a Fuzz Face between his Les Paul and his Marshall. But subsequent listening and reading makes me believe I was wrong. So I figured it was time to play fuzz detective and sort the facts from the other stuff.

First, I made clones of all the early commercial fuzzes. I’ll be posting a compare-and-contrast video in the coming days. (The audio forensics will be quite incriminating.) Here’s the lineup:

The usual suspects. (Incriminating audio/video evidence to be posted soon!)

I’ve also re-read the experts, and man, even my most trusted sources contradict each other right and left, especially when it comes to those darn Tone Benders. While I have absolutely no inside dope on what actually transpired, I think David from D*A*M Stompboxes offers the most convincing Tone Bender chronology, which you can read here.

Anyway, here’s my best guess about how the early fuzz years unfolded:
