Great question! I'm VERY partial to my Epiphone Les Paul Goth. Mahogany body, hot pickups. Great harmonics and sub tones. Look for a guitar with a thicker body. Most inexpensive Guitars skimp on the body materials so it may be better to spend your $$ on something used but higher quality.

Bass, clean guitars,distorted guitars drums, vocals
Mahogany or Alder.
Gibson SG
An electric guitar
There are no best harmonics.
A rythym guitar is an electric or accoustic guitar playing chords to keep rythym and the bass guitar is used to anchor down the harmonics and lay down the beat, basically smooth things out and either playing basic rythyms or beautiful harmonics.
This depends on what type of guitar you are using. If you are using an acoustic guitar then reshaping will harm the sound. If you are using an electric guitar it will not, but you must have the strings set to the same tension after you have reshaped it.

Les Paul
It depends on personal preference classical music would be best played on a classical guitar, metal would sound best on electric acoustic is a different sound so it is up to personal preference

Harmonics is electric current or voltages that are part of the power system as a result of nonlinear electric loads. If there is no load and a harmonic is present it can present because of a rectifier in the system.
