Re: Does neck radius matter for soloing?
The flatter radius is great for bending (especially Blues), and playing fast solos. However, a rounder radius is better for chording, chordal comping, chickin' pickin', and other types of non-rock-shred stuff. Guitars that have rounder radii also tend to have thicker necks which help to support your hand. More support = less fatigue. If you're a bedroom noodler, it won't matter much, but if you're playing 4 sets twice a week, you'll appreciate the extra support by the end of the night. You might not be 'thinking' it, but you'll definately be feeling the benefit.
My reissue Tele (7.25" round radius) is great for all the Country type playing, and Bebop, Funk, Rock-a-billy, etc. The action is a bit higher since I pick, and/or pluck, the strings pretty hard. With the action set a bit higher, the notes don't cut out when bent.
My American Standard Tele (9.5" radius) has a slightly flatter fretboard, and is a great all-around guitar. The action is kept lower for easier playing, but the notes do compress a bit when I nail the strings a little too hard.
My Les Paul, and PRS Custom have MUCH flatter fretboards and thin necks. I love them for the hard Blues, and Rock stuff. I can solo on them without giving it a second's thought. The notes NEVER cut out when bending, even with crazy low action. Again, I can't nail the strings too hard or they'll compress on me. When I run the action at 3/32" or so, they hold up very well. Both will go lower, but then I have to tread lightly.
I play with heavy Gibson heart-shaped picks, and use my middle, and ring fingers to pluck. In a nutshell, I think Fender nailed it with their American Standard series guitars. The radius feels 'just right'...........too me anyway.
