I've played a couple types. The Fenders seem to have that baseball bat feel .. 9.5" I think it is. My early Cort A4 (early style w/2 pc bridge+tailstop and no EQ on-off toggle switch) has a pretty flat one, 15.75" or 16" or so. I've come to love that silly Cort over the last ten+ years but I'm kinda curious as to what each radius is actually designed for? My previous Carvins all had pretty flat boards. Opposing that idea, I see Warmoth pretty much offers only 10" boards. Now that I think of it, it seems like every neck-thru I've owned was pretty flat, and every bolt-on has been the rounder 10" range. Wait, don't remember what my Rick 4003 was like though. Meh .. whatever. Other than the obvious answer of "it's just personal preference man!" is there some sortof specific reason for one fretboard radius over the other? If it matters, I pick and finger, but do not slap. I'm left but play right. Done 4, 5, and 6 strings .. long scale/short scale ... I'm right back to 4 strings/34" scale these days. Thanks!
