The actual effect that I'm going for, wow, is caused as I can best understand it, by nonuniform movement of the magnetic tape within a deck. It causes slow periodic deviations in the pitch and speed of the sound. Flutter is the same thing except alot faster. I'm wanting to go for a strong wow effect.
I've listened to some of the samples of some of the Electro-Harmonix line of pedals, namely the Worm and the Wiggler, that I think might work, but I can't really tell unless I'm able to sit down and really play with each of the pedals.
I suppose I need to find the right pedal, or combination of pedals, that allows for variant delays and deviance in the pitch to simulate the effect.
