Here's an intriguing early NAMM release: Modern Guitars Magazine reports on Hot Hand, a $299 effects box which is controlled by a finger-mounted sensor. Wiggle your finger in different directions, and the effects change. Initially, the effects are various wah/filter effects. As it's designed for guitarists, I guess the idea is to have it on your right hand, strike a chord and wiggle a bit. It's produced by a new company called Source Audio (not an easy name to Google), which is a spin off from Analog Devices, who make the chips inside lots of synths. They're planning more products and the Hot Hand itself will be upgraded to do more than just wah effects. (Thanks to Keith from EmulatorXone)
