Sound samples	Dry electric guitar signal #1 An unprocessed electric guitar signal as directly recorded by the sound card. Simulation with nearly linear model a = 9.. Simulation with small amount of transformer saturation, a = 90. Simulation with Fender transformer model, a = 900. Exagerated simulation, a = 9000. In the sound samples above, both amplifier simulations, the commercial and WDF-model, also provide a loudspeaker emulation. In the case of our WDF-model, the emulation is a simple lowpass filter with cutoff frequency at 5 kHz and a 6 dB notch at 1.2 kHz.
