Misa Digital Guitar makes your Rock Band Peripherals feel inadequate (PCWorld)

It's a nice little gimmick, but it is somewhat pointless. A guitar player already has a lot of opportunities for tone-shaping by playing techniques such as bending (and many more), plus a bewildering array of effect pedals.

A touchpad for effect control makes more sense in the keyboard world, where opportunities for shaping the tone with your fingers is much less, being reduced to attack, pitch wheel and tone wheel.

A good musician has already control over many more parameters than the Misa Digital Guitar can hope to provide.
