Leo Fender's Telecaster was the design that made bolt-on neck, solid body guitars viable in the marketplace. Fender had an electronics repair shop called Fender's Radio Service where he first repaired, then designed, amplifiers and electromagnetic pickups for musicians — chiefly players of electric semi-acoustic guitars, electric Hawaiian lap steel guitars, and mandolins.
To my ears a rosewood fretboard neck is brighter than a one-piece maple neck. The one-piece neck has a certain drive in the upper mids where your ears are sensitive (this is why many say it has more attack and sparkle) but true treble is the rosewood neck's domain.
For example, I've had 2pc Southern US swamp ash Tele bodies that weighed as light as under 3# and as heavy as over 5# - and the heavier ash bodies reliably produce a guitar with more treble influenced tone whilst the lighter and more resonant ash bodies typically produce a more mid-ranged and harmonically enrichened tone. Same wood origins, completely different sonics.
