Great question. Impossible to narrow it down!
Early in my music career, it was the blues greats. Anyone with a last name King, SRV, Jimi. In college, I learned about Wes Montgomery, Kenny Burrell, Pat Matheny. Then I started writing music and learned from JT, Paul Simon, Carly Simon, and many others.
More recently (the last decade) I've focused on jam band music so I've been influenced by Derek Trucks, Warren Haynes, and Trey A. Also the sick modern blues players like Joe Bonamassa, Eric Gales, and John Mayer.
And also the great local/regional players I used to gig with/open for back in Chicago. Chico Banks (taken way too soon, RIP). Biscuit Miller (Who still gigs out Topdown's way from time to time). Stan Skibby.
It's difficult to answer this question concisely.
