While I haven't consciously pursued blue guitars they seem to have come my way. These two have come courtesy of Brett at Eddie's. The newest is the WL 594 with the rosewood neck and cocobolo fretboard. The color is River Blue and the back is a dark Tobacco transparent that allows the grain to be seen. This wood combination is resonant and I am amazed at much vibration I can feel in my fretting hand and how long that vibration lasts ... noticeably longer than with the mahogany neck on the other 594 10 top that I have. I never would have thought about cocobolo as a fretboard wood but it pairs nicely with the EIRW neck and offers a nice separation of the treble notes. Very happy with the WL choices! The Santana is a Faded Whale Blue with a black back. I am continually amazed at how Paul's passion is evident in his guitars.
