In the course of the project a commercial
available analog guitar effect
pedal, the ’Pharaoh’ fuzz by Black Art
Toneworks, has been thoroughly analyzed
and tested. Based on this a
digital model has been developed and
evaluated. The model has been based
on numerous recorded analysis signals.
The recordings were emulated
by the use of a transfer function to
simulate the waveforms. Insight of
how the Pharaoh fuzz works were obtained
through a circuit schematic and
SPICE simulations thereof. The developed
pedal is able to produce very
similar waveforms in accordance with
the analysis recordings. A qualitative
evaluation of the simulated effect
pedal was conducted with two guitarists.
Both found the pedal considerably
similar to the Pharaoh.
