Because guitar amps usually have 10, 12 or 15 inch speakers (from 1 up to 8) and rather large cabinets the correct EQ should probably be a high order (8 to 12) butterworth lowpass at somewhere between 4Khz and 10kHz to accurately model the frequency response of the speakers and cabinet. > I haven't forgotten about the compressor, I just haven't worked up the > energy to tackle it yet. I have a rough hack of a compressor (but nice sounding) I'm getting ready for a tutorial I'm presenting at Linux.conf.au in a couple of weeks. I should probably downlaod the LADSPA stuff and see if I can create a plugin. My compressor currently has: - switchable feed-forward / feed-back architecture - attack time - hold time - release time The attack and release timers currently do exponential ramps, but I should also look into doing linear ones.
