Right McGrath. That's a great chord I just discovered recently.I mainly barre, but that's just the way I learned. What's great is that once you're comfortable there's a world of chords there. But I have come down with some huge cramps, especially playing with sax players; all these tunes in Eb.
I started adding the wrap to my playing as I went through a Bruce Cockburn songbook, and jsut found many chord voicings where that was the way to go. since then I've found lots of times when it works great. No right or wrong; just what works.
by the way; check out Jimi hendrix sometime if you want to see some major thumb work. And HUGE friggin' thumbs. SB
