I could not bare to be separated from my new guitar anymore, so I took a 2hrs bus ride in order to go get it before friday. It plays great now, neck is adjusted properly, frets are leveled and polished and strings are as low as they can get, even too low for my taste, will need to raise them a bit by myself. Luthier said that he had hard time leveling the frets, because the fretboard was not shaped properly, it is uneven, resulting in him having to file some frets a lot, while others not at all. He said that he could not fix that without replacing all the frets, but that in his opinion it is not necessary at the moment. It is an issue, but not a major one. He says that i should play it like it is, and when i wear down the frets enough to have them replaced, he will sand the fretboard properly before replacing them. He charged me 30e, because the pot didnt need replacing, and Im pretty happy now with my guitar. Had to jump through some hoops to get here, but it was worth it.
