@gabaghoul , like others have said you can change anything you want and it’s good to explore all the options. If you want to learn luthiery or just mess around it’s probably better to do it on something cheap that doesn’t matter or else get somebody good to do it for you or else advise you on how to do it.
My 2 cents worth?
The label on the headstock, or lack of it, the finish, or lack of it, the “feel”, whatever that is, don’t matter. As long as it stays mostly in tune and doesn’t have any dead spots or a lot of “wolf” note issues you’re in the ball park. Hardware makes a difference but that’s easily changed so it’s not important either.
What’s important on a glue neck guitar (bolt-ons are different) is the body, neck and the glue joint. It’s the wood and how they interact and it makes a big difference. Each one of these guitars is a unique combination of those three elements You need to try a bunch of them at the same time, acoustically and through a decent amp and do a lot of listening. At some point you need to try some high dollar old Gibsons for a reference point. But remember there are some great players who are happy with no-name guitars. It’s all about how that wood stuff sounds to you. Get that part right and it’s easy to learn what different hardware (strings, picks, and amps too) sounds like.
One disclaimer here, I’m excluding the world of digital modeling from this rant. That’s a whole different ball game.
Just my 2 cents worth.
