what is dis/advantage over a two piece?
normally you wouldnt have a two piece neck. More common would be three-piece laminate, or 5piece laminate (5piece usually uncludes this setup...say with maple and bubinga for example..M/B/M/B/M, or somthing of that sort) but I believe a lot of it has to do with neck strength.
why is maple a good/bad neck wood?
a lot of it is preference of look and sound. Maple can look very nice, and the sound is bright and crisp, and it's used on many guitars.
why is bolt on good/bad?
well theres lots of opinions on this. Bolt ons can come loose, whereas like my gluedon gibson neck is not gonna come out, but my strat copy neck can come a little loose.
why is the brand good/bad?
never heard of that brand
why is C shape good bad?
uhm C shape is the basic neck shape, some ibanez's and jackson's necks are a lot thinner and even can be curved towards the top and bottom and flat in the middle, but C shape is basically the shape of a neck...also provides good control because you have a lot to grip onto (if it's a thick C neck)
