Our local musical instrument dealer still praises Samick after some 25 years since the first ones came to his shop. They have to be a good quality manufacturer as they have built instruments for many big names including Yamaha, Ibanez, LTD, PRS, Epiphone, Jackson... Not Fender, though
Price or brand doesn't tell how well a guitar plays. The best guitar vendors adjust every guitar they sell as the factory setup rarely is good enough. Often the nut has been left tall which makes chording a pain. The fret ends may also stick out, either because of poor filing or shrunk fretboard. The intonation may be off, the truss rod loose as well as bolts and screws... Some issues may be intentional to be fine tuned for the actual player, some may be because of climate changes during transport and some may be for eliminating tension related problems during transport. Shortly put, a well set up guitar plays well.
Regarding sound, the sound of the solid body guitar comes mostly from the pickups. The neck has an effect to the sustain which is part of the tone, it also affects the overall "feel" or "responsiveness" as it vibrates. The player has a big role as well - you can't really judge the sound of certain guitars by hearing each of them played by a different player! Just give me any great guitar and it will say "thump, thump" when I play it! And lastly, the body has quite a minor part in the sound of a solid body electric.
Congrats for a great instrument!
