The neck profile is a hand shaped soft "V" profile on a medium chunky neck (.88 at the 3rd fret), and 1 3/4th Wide Nut with wide string spacing, I hand roll the fingerboard edges so the neck feels broken in when it's new. I use medium jumbo frets with a modern 12 inch radius. These dimensions are the best blend of acoustic and electric guitar specs for excellent playability. The slight V make chord changes smoother and easy. Perfect for fingerpickers and blues players.
The medium chunky (not huge) neck is part of the Talkovich design. Larger necks provide a stable platform for string vibrations and larger necks allow for great consistency in my guitars, they just sound better. More the mass, much less chance the slight natural variations in wood density will create dead spots.

Current (2010/2011) neck backs are satin nitro lacquer for a silky, no drag feeling, there's no break in. The headstock is finished in gloss nitro lacquer and it's always applied directly to the wood in thin coats. I apply thin coats over a longer period of time to allow the previous coats to sink into the wood and gas out. This method helps me apply just enough finish rather than load the wood up with lacquer. (The same process applies to bodies).
The 1 & 3/4ths inch wide nut w/ wide string spacing and soft V neck dimensions blend together for a fast neck with improved string control. Fingerpickers and flat pickers appreciate the extra real estate with extended string spacing at the nut. My necks have a top adjusting truss rod, frankly, it's impossible to adjust a heal adjusting neck properly, it's just a bad design. Experienced players know the subtle differences slight adjustments to the truss rod can make, and your chances of getting it right are greatly improved adjusting with the neck on the instrument.
