What is your definition of an equaliser? How much control do you want to have? How exact should the control be? How much distortion is allowed? For a guitar with at least two single coils you don't need an RC element to get a tone control. You only need two switches. Just use on of the coils, use both coils or use both and change the phase of one coil. So two coils and two switches = 4 sounds. Instead of using 2 switches, you could change the distance between a pickup and the strings, then you could consider the "equaliser" would be a screwdriver, but actually it's physics. keywords are "time domain", "insulating material" etc., e.g. move your hand in front of your mobile's speaker to get a wah-wah. https://en.wikipedia.org/wiki/Electronic_filter https://en.wikipedia.org/wiki/Distortion#Harmonic_distortion http://www.premierguitar.com/articles/phasing-out-how-to-get-out-of-phase-sounds-from-a-stratocaster-1 Do you need a processor and RAM for an equaliser? For a digital equaliser you need a processor and RAM. For an analog equaliser you don't need it. To control the tone you need a tone control. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
