tremolo, vibrato, reverb

[Jerryz1963]

I saw this uber-expensive stomp box that said it does all three, reverb, vibrato, and tremolo. The description of the product indicated that this was accomplished by outputting a sine wave, square wave, and triangle waves.

Is this correct? 'cause I don't see how that is hundreds of dollars worth of stomp box. I have some ICs I was meaning to implement for a reverb and last night I was studying the data sheet for it. fascinating possibilities. It is sort of two oscillators in one. By applying a high or low voltage to one of the pins, you can activate one oscillator or the other. So, by applying a varying voltage to that pin, you could actually make it alternate between the two frequencies at a rate (or frequency) determined by the waveform applied to that "switching" pin. So I asked my guitarist buddy, and he said that yes, that does sound like something a guitarist would use, but he's not an electronics geek and I'm not a musician, thus a bit of a communications impasse.

These days with the cost of IC chips if you pay more than 200 bucks for a stomp box that has only those 3 features, then you are paying for low production numbers, eye candy, or both!!
And hopefully build quality is in there somewhere!
