Stevie Wonder's classic was on a list of tunes for a wedding I'm playing, and believe it or not I've never had to play it before, so I figured it was a nice excuse to learn it. That Clavinet part is SO FUNKY! I've been having a ton of fun with it. Plus I'm playing it on the GWB1 fretless with her new ACG preamp. The tone just KILLS - period, but especially for that song and groove. It's got that Wal-y, Clav-y nasal grrrrrowl. I am lovin' life. I realize I'm starting to sound like a freakin' shill for Alan at ACG, but I'm not - just a dawg lovin' the sound he's getting from his instrument.
