From what I found, when you see the same guitar but one is way more expensive than the other, it is probably something cosmetic.
Not exactly.
There are many high end guitars that look more "plain jane" than the entry level guitars. It's all marketing demographics.
There will always be way more cheap guitars being sold to the curious than high ends guitars being sold. Although guitar construction is basically the same, the materials used will affect the tone for better or worse.
Cheap entry level guitars are all laminate including the top. This means that the beautiful wood you see is a veneer that is glued onto some piece of wood. These guitars are durable, and are not that sensitive to temperature and humidity changes but seriously lack in the tone department. The term "plywood guitar" comes to mind.
Mid level guitars ($500-$1000) tend to have a solid wood top w/ laminate back and sides. Since the top is 90% responsible for the sound, the sonic qualities are heavy in the midrange to high frequencies but lack some umph.
High end are all solid wood. Front, back, and sides are solid. They are very sensitive to humidity changes but the sonic properties are usually very wide. Deep clean lows and sparkling highs.
When you say same guitar, do you mean a certain style Dreadnough, Jumbo, Grand Conert, or do you mean brand name Gibson, Taylor, Collings, Martin......
