Maple vs. rosewood neck
Because of the numerous aspects that influence the sound of a guitar, it is pretty complicated to describe the tonal alterations caused by different neck materials.
The way the guitarist pulls the strings, the pick, the material of the strings and, of course the frets definitively affect on the tone.
And, in addition, the wood of every tree is unique and therefore varies in a certain way.
The maple necks from a different batch sounds a bit different.
Generally speaking, maple sounds a bit more percussive and filigree while rosewood produces a warmer and fuller tone.
The effect of the body material is even harder to identify.
A guitar builder once told me, that 90% of the tone in fact come from the neck and only 10% from the body.
If you also take the differences between every single piece of wood into consideration, it may become impossible to describe the tonal differences of guitar body woods.
And, also the quality of the wood has a decisive effect on the tone.
Gibson custom shop guitars, as well as cheaper Chinese copies are made of mahogany.
The custom shop uses selected wood that has been stored for a long time and chose because of its tonal characteristics.
The cheaper Chinese copies of the American classics are made of low-priced wood, mostly glued together to one piece.
Doubtless, both manufacturers tell the truth by advertising that they use mahogany, but the tonal differences are enormous.
Most likely the effect from the body wood on the sustain can be figured out.
Mahogany is said to produce more sustain while a maple top provides more attack.
Most mahogany guitars have a set neck instead of a bold-on neck, though it is doubtful whether this kind of sustain origins from the wood or perhaps rather from the way the neck is attached to the body.
Pickups, pots and wiring
Finally, the tone of the wood passes the pickups, the cables, the pots and numerous pedals until it reaches the amplifier.
All this also influences or even adulterates the initial tone.
Regarding the selection of a guitar you should not only take the tonal characteristics of a certain wood into consideration but also try the instrument with your own equipment at home or in the rehearsal room.
Since, what is a good sounding neck or body good for, if you need countless modifications to optimize the sound of the guitar in your personal setup?
