what exactly does a ring modulator do? (he asks hoping its not a stupid

Well, if a Maestro ring modulator is anything like a JEN ring modulator, it does something kinda like this:

You have a signal that you run through the ring modulator, say guitar or organ or what have you. The ring modulator has an internal oscillator which you can control speed/tone/depth on. The sound that is output is the product of the two waves.

You can achieve some truly spectacluarly messed-up sounds with it, everything from bell-like tones out of your guitar to wonderfully overdriven rippling organ tones. It tends to really make chords sound muddy and unintelligible, but that's what some people want. The nature of ring modulators seems to make them work best with single notes/voices.

I've heard people refer to them as "Sonic Youth in a box", and was told that the last time they were in LA, the 'Youf themselves bought up an armful of them. Whatever.

I don't have a price point on one of the Maestro units, but my JEN (which had been sitting in a warehouse in Italy since just after i was born) cost me about a hundred bucks at one of the better (if not best) LA music dealers. They still had four of them, last i checked.

you take the product of two waves. this contains lots of additional harmonics. if the original frequencies were f1 and f2, the product will contain f1, f2, f1 + 2 * (f2 - f1), f1 + 3 * (f2 - f1) and so on, also to the other side. calculational proof: do a fourier series expansion of sin (f1 x) * sin (f2 x). (the expansion of sin (f1 x) - sin (f2 x) just contains f1 and f2.)

is this math rock or what
