Newly available (Spring, 2014): A custom Univox Super Fuzz clone - the "Anubi-Fuzz Classic"


I'm going to initially make 12 of these, and you can order one (special intro price) for $99 + shipping.
If these become popular, I will order more parts to start on a second batch.
This is a handmade clone of the Univox Super Fuzz (guitar effects pedal) which was produced from the late 1960's
into the 1970's. There have been many other clones of these over the years due to it being a very sought-after circuit,
and these are still very popular due to the sound and versatility of its effects.
I've been calling these "Anubi-Fuzz" in honor of Bill MacKechnie, lead guitarist of the band "Anubis Spire" (see link at bottom),
who had been trying to talk me into making these for many years, and to whom I sent the first successful prototype.
Bill is an avid collector and designer of guitars, especially for Raven West Guitars. He said that the sound
of this pedal reminded him quite a bit of a classic pedal he used during the recording of his album "Old Lions".

From Wikipedia:
This unique fuzz tone is an octave fuzz using two germanium diodes to produce the square wave clipping.
The controls are 'Balance' (volume), 'Expander' (fuzz amount), a two position 'tone' switch,
and an on/off footswitch on top. There are two unique features of this device that set it apart
from other distortion and fuzz pedals. The first is that the full-wave rectification of the circuit
produces an upper octave as well as a slight lower octave. This also gives the sound
a lot of compression and gives a mild ring modulator effect. The second unique feature
is a tone switch that engages a 1khz filter that "scoops" the mids, giving a very fat,
almost bassy tone, unique to this circuit.

The circuit is composed of 52 components on tiny circuit board approximately 2.5 x 3 inches,
including 6 transistors & 2 diodes. In this batch, I'm using five metal-cased 2N2222A transistors
for the main part of the circuit, and a 2N3904 as the final (amplification) transistor.
I'm using a pair of Germanium 1N60P diodes for the clipping diodes, which have the same effect as those
in the original design. It's enclosed in a custom orange heavyweight cast aluminum case,
approximately 3.5" x 4.5" x 1.3" deep. The two-position tone switch is a mini-switch, and the
9 volt battery (included) is attached to the cover with double-sided tape in the space
above the two controls (top right of the case looking from the top). The two controls,
"Balance" and "Expander" are at the top right with aluminum pointer knobs.
"Balance" will equalize the volume to the volume of your guitar when the circuit is bypassed,
and the "Expander" controls the amount of fuzz with the circuit kicked in.
In addition, there's a rear power jack if you care to use a "wall wart" instead, this will bypass
the battery when inserted. You will need to use a "center negative" DC 9 volt regulated power supply (not included)
such as the Morley 9v "Universal Effect Pedal Adapter" which works with most other vintage pedals as well.
The unit is turned on by inserting the plug from the cable coming from your guitar into the right-side
input jack, and a small green LED indicates that the unit is powered on. The alternating footswitch
(click-on, click-off) determines whether your music goes through the circuit or is bypassed and goes
directly to the amp. Here are some photos of how these are made in my basement workshop:

I will be building these one at a time in the next few months, so please contact me
stating your interest so I can determine the pace at which I need to go to fulfill orders.
You may also send a small deposit to establish a position in the order queue. Thank you!
Contact: Frank F. at to order.

Thanks for stopping by to visit this site, and please pass it on...
