Body Types of the Electric Guitar
Electric guitars come in three fundamental body shapes. The construction decides weight, resonance, sustain and how prone the guitar is to feedback at high volume — all of that is set before the amp is even switched on. For the amplified tone the body shape matters less than the pickups; for feel and stage behavior, a great deal.
Solid Body — A solid wooden body with no resonating chamber. That means maximum sustain, minimal feedback, and a weight you notice at the end of a long night. It is the standard for anything loud and driven. Reference models: Fender Stratocaster and Telecaster, Gibson Les Paul and SG. The Strat is often called the best-selling guitar model ever — slim and versatile; the Les Paul is heavier and warmer, with long sustain from its mahogany body and maple top.
Semi-Hollow — A hollow chamber with a solid center block. The block tames feedback while the chamber keeps a warmer, airier character. That makes this the most versatile shape for blues, jazz and rock alike. Reference: Gibson ES-335, Epiphone Dot.
Hollow Body (Archtop) — Fully hollow, maximum acoustic resonance and a full, open clean tone. The price: at higher volumes it becomes feedback-prone quickly. Reference: Gibson ES-175, various Gretsch models. At home in jazz and country, less so in loud rock.
An honest note on choosing: no body type is "better". They solve different problems — loud and feedback-proof versus warm and resonant. Anyone who stands and plays loud will notice weight and feedback behavior more than any tonal difference in the wood.
