UNION TUBE & TRANSISTOR: Bumble Buzz

The Bumble Buzz is based on the Kay Fuzztone, which is a simplified Univox Super Fuzz.  It's a collaboration between Union Tube & Transistor and Third Man Records (Jack White).

There are no knobs; just stomp and go.  Raw octave fuzz....

I should have cleaned up the edges a bit - but hey...  it was a quick and dirty build.

ON THE SCOPE / FFT

440hz sine wave, approx 130mv TRMS

A very distinct octave can be seen, along with a lot of high-frequency content.  As you can see, the actual trace here, is almost identical to the LTspice sim shown below.
