I was wondering about this thing. Usually all teh Bass effect pedals or multi-processors are more expensive than guitar. So like whats so great about them? The only thing I can come up with is that the Frequency response of Bass would be much wider. Guitar's Low E string produces fundamental 84 Hz Bass's low E produces 42Hz So does that mean that Guitar FX have a low cut off ~ 84Hz, which makes them useless for Bass?
