actually mate.
I have a real problem with this....
first the above is the first post you have made on here. What's your motive man? Is it just trolling, or just wanting to vent about something?
second. you're not asking for advice. You make statements and you video is just slagging them off.
third. you don't seem to understand how a maple fretboard neck is made, and the techniques for finishing it. You could come on and ask people, and there are many builders who could tell you - but no instead 'overwater are the only people stupid enough to make a bass like this' (I paraphrase)
fourth. - and this is the main one for me. How old is this bass? It comes across that it's a new bass that you had made and aren't happy with. And in which case take it back..... except it's not is it? Theres a video a year old on your youtube channel with the same bass being played. And fantastically you seem to have no problem with the first fret back then.
so tell us, how old is the bass.
and more importantly have you, or anyone else, had any work done to it since it left the factory?
cos to me it looks like it's had a fret dressing or two... which of course makes the frets lower and closer to the laquare... and would possibly explain why it sounded fine a year ago.
And the answer to your next question is yes, refreting a maple board costs more as the neck has to be relaqured. and that's true of any make. If I ground the frets of my P bass down to speed bumps I hardly think it's the fault of the japanese guys who made it 30 years ago is it?
