I remember my first custom made guitar and the neck.
always one to do a bit of tinkering, I played a friends guitar and he had the finish removed from the back of the neck, then a small veneer of varnish applied
so I got out the sandpaper and did the same.
it was smooth and felt great
now here is a different concept altogether

I like the way the top curves away and it looks pretty light. the input jack is a good idea, giving you the ability to put the lead through your strap with ease.
but we are focusing on the neck and here is an example of what I am talking about
let's take a closer look
an engraved pattern on the back of the neck that reduces the friction of the thumb.
to quote, "reduces surface area by 70% and putting a bit of air between you and
your guitar...your hand only comes in contact with 30% of the neck"
looking at it, it seems to make a lot of sense
