Color choice guitar neck: the type of wood used on top of the guitar neck (fretboard) is very important for the sound.
A pale neck (often maple) as often used with Fender Stratocaster or Fender Telecaster, in my experience has a somewhat sharp, shrill and more aggressive sound. For example, a pale neck is ideal for aggressive funk and blues. I’m thinking of Jimi Hendrix, Red Hot Chili Peppers, but also guitarists like Eric Clapton and Mark Knopfler play on a Maple Strat. A dark neck sounds warmer and softer, often used with Gibson, Ibanez, some Fender guitars, ESP, Music Man, etc.
So is guitar neck color choice important? A dark neck sounds better for warmer sounds in both pop music and more heavy styles. In metal, for example, you will not easily see a pale neck. But the choice of guitar neck is also something personal, and many guitarists have both in their guitar collection. In terms of maintenance, a maple neck is much less fragile and requires less maintenance than, for example, Rosewood (rosewood). But yes, anyway, go to the music store and try out the difference for yourself!
