Yeah, the first Warmoth neck i purchased was kinda fat, bassball bat like, So I sanded it down a bit to my liking, it felt a lil better,but it was still pretty chunky (Be careful not to sand too much it'll effect it's tone!) however, on my next order/purchase. I ordered one with the "slim taper" profile option, and that Is awesome/perfect, more C than D and "jazz like", totally worth it! I also found their necks to be quite heavy,with their std. steel rods (which i believed caused head/neck dive & i didn't feel like shelliing 60 more for the graphite rods), But changing to hipshot ultralite tuners Fixed that problem!!
I highly recommend their custom necks, especially with their Slim taper profile option(super sweet)!!
Also, just a few more words(sorry lp).they'll need a little fret finishing work, but nothing too serious. i did it on my own. just a little filing to round over the fret edges (lil sharp fret ends nothing more).... i did it my self to my liking. now they're perfect. yeah, it's a little annoying to pay good $$ for a custom neck, and have to finish it yourself or just pay a tech to do it. its not a big deal. I love my Warmoth Necks! totally worth the extra effort! good luck.
