Hope this isn't off-topic enough to warrant making its own thread. How would you go about making a neck feel lass tacky/sticky?
As the others mentioned, clean it and wax it if you have a gloss or satin finish. If it's oil, smooth it out and re-oil it. One thing to note is that if you have less surface area contact on the neck, you might notice that finish or a lack thereof is no longer an important factor. With the bulk of my technique being transferred from classical guitar, only the thumb print area of my thumb contacts the neck. If you're wrapping more of your hand around the neck, there will be more surface area contact and the gloss will add more resistance.
I personally prefer a satin finish because it feels kinda like an oiled neck, but is much less work overall and less sensitive to the elements. I still have a few oiled necks, but decided I have enough because it's a lot of work when I need to oil several necks and one entire body. I still have a few gloss necked basses, but I notice they don't feel as clean sometimes and I tend to polish and wax them more often, even though a little funk won't slow me down.
Right on. I allways get anoyed when people think they need a toothpick ibanez neck to play fast.
I'll agree that neck profile isn't as critical as many make it out to be. One advantage of a thin neck is that it will force you to play with your thumb down the center because wrapping your hand around the neck becomes more difficult and uncomfortable. The ideal hand positioning still works on thicker necks, although neck dive more or less forces the left hand to shift into a position that supports the bass and will use more of that undesired thumb over technique, which can drastically slow down the left hand and add fatigue with other joint/neural issues. I could definitely see a thin neck being somewhat painful on a neck-diver. On a wide 5 or 6+ string bass, thinner simply becomes a necessity due to the overall size of the neck.
I personally prefer a thin neck, but a lot of that is for weight reduction. It weighs a lot less if there's less wood out there.

My Rob Allens have some pretty beefy necks, but the overall shape is still comfy, especially with the reduced reach.
.....so you see, it's all related some way or another.......
