Part of the Reason experience for me is the opportunity to learn and grow my music skills, and find inspiration from others in the community.
It is really excellent to have such talented folks give up their time to help us all learn here, so just wanted to call out Giles Reaves aka Selig as one leading example here.
Probably most of us have benefited from Selig's advice - and Rack Extensions, but I'm not sure if everyone knows his credentials.
A couple of links to check out. (Hope you don't mind Selig!)
