really cool, but no song on the album was close to it,
so we focused on creating a device that recreated the
tube's saturation and abandoned the idea of including
the fuzz circuit in the Dr. Robert.
Eventually one day, we came across a Youtube demo
where a Vox UL730 was being showcased, and its
fuzz tone was nothing like our amp. It had a lot more
sustain with no gated component, which made us
wonder what was the cause of such a dramatic
difference. We reopened our UL730 and after checking
several components in the circuit, we found the
culprit! As time passes, some components lose their
properties and shift their value out of their specified
tolerances. That led to an underbiasing of the fuzz
circuit and caused that starving and gated tone!
While we were re-analyzing the amp, we looked for
the same diodes used on the UL series and found
a surplus lot of 400 N.O.S Phillips OA200 diodes, a
very rare component only used on that amp series.
We couldn't believe how lucky we were, because that
meant that at least we could make a small run of fuzz
pedals!
With the mystery solved and the right component in
hand, it was time to create what would become The
Mocker!
As we found both sounds equally cool and useful, we
developed a prototype which featured a bias knob to
dial between a great variety of textures, from gated to
