Abstract
I dette projekt er en kommercielt tilgængelig analog guitar-effekt, fuzz-pedalen 'Pharaoh' fra Black Art Toneworks, grundigt analyseret og testet. For at forstå pedalen blev dens kredsløb gennemgået via diagram og simuleret i SPICE (et værktøj til kredsløbssimulering). Med udgangspunkt i mange optagede testsignaler blev der udviklet en digital model af pedalen. Modellen bruger en transferfunktion (en matematisk beskrivelse af, hvordan input omdannes til output) til at genskabe de observerede bølgeformer i signalet. Den udviklede model kan producere bølgeformer, der ligger meget tæt på optagelserne fra analysen. En kvalitativ evaluering med to guitarister viste, at den simulerede pedal opleves som betydeligt lig den originale Pharaoh.
This project analyzes and tests a commercially available analog guitar effect, the 'Pharaoh' fuzz by Black Art Toneworks. To understand how the pedal works, its circuit was studied using a schematic and SPICE simulations (circuit-simulation software). Based on many recorded test signals, a digital model of the pedal was developed. The model uses a transfer function—a mathematical mapping from input to output—to reproduce the observed signal waveforms. The developed model generates waveforms that closely match the analysis recordings. In a qualitative evaluation with two guitarists, both found the simulated pedal to be considerably similar to the original Pharaoh.
