Guitar 1
Guitar 2
make sure you read the details of each guitar, then look at the price of each guitar.
one is 80 dollars and one is 2000 dollars.
please explain to me why one guitar is 1920$ more than the other
Everything is the difference. Yes they have similar shapes and are probably built on similar machines. But that's where it ends.
The $80 guitar will have poor quality everything - right down to the wiring inside, the chinzy components, the metal used in the hardware, the cheap magnets in the pickups, the fret wire, everything. The grade of wood is also poor in cheap guitars (even if they claim to be "solid" wood). The fretwork, the fitting, the factory setup etc etc etc. You can mitigate all of these factors by swapping out everything and correcting cheap fret jobs etc, but by then you are pretty much making a guitar yourself (and it will cost a fair bit in hardware, tools and time).
The $2000 guitar will have better everything to start with. The price difference comes from time spent in the factory, the skill of the workers there etc. The components inside aren't really the difference (okay maybe a few hundred bucks in manufacturer dollars). Proper work takes time. Time costs a lot.
Consider this: The final price includes all the manufacturing cost (parts and labour) AND markup for all suppliers at a profit. Working backwards from that, the $80 guitar needed to be made for significantly less, and everyone had to get paid, machines had to get paid for, all that stuff, it's actually quite amazing.
I've fixed many many a cheap guitar in my time and yes you can totally get a workhorse from a cheap guitar, some good parts, some fretwork and a good setup - but when you play good high end instruments the difference is very clear. The one thing that I think makes this difference apparent is the grade of wood (considering it's the only thing you can't swap out).
A bit off topic, you can get a great, cheap guitar, completely customized, through Warmoth for cheapish (depending on your wallet and tastes) and you'll get far superior instrument to the USA Fenders (which don't get really really good until you start spending $4k hehe).
Just my 2c!
(for the record, I consider "playable" very different to "good"... I bet you could get the $80 guitar to play and feel great - it just won't sound much chop)
