I stripped the black burst finish off one of my old Teisco necks and used like 10 coats of boiled linseed oil. It looks and feels amazing. I’ll see if I can find a picture.
I've only finished a raw Musikraft Maple neck with TruOil. My limited understanding is that TruOil is more like a varnish in that it dries and creates a hardened finish. The Musikraft neck I did feels like it has a finish on it. I wet sanded it with TruOil (thinned with a tiny bit of Turpentine) and went thru several grits until I got up to 2000 grit. It is extremely smooth and feels/looks good...but it still feels like a finish. I don't know what Chubtone uses but my Chubtone feels much more like raw wood. My D'Avanzo is somewhere in between in that it feels less raw than the Chubtone but still feels like wood instead of 'finished wood'. I also have a Warmoth neck that had the glossy finish sanded off and then just a tiny bit of TruOil. It feels similar to the D'Avanzo.
Which one do I like best? Lol, whichever one I'm playing at the moment (except the Musikraft). They all feel good. I'll probably sand the Musikraft down and just put a very light coat of TruOil and wipe it off and that's it. I've sanded that fucking thing enough!
I did a Fender neck with tung oil years ago. Stripped, sanded no sealer. Turned out great and felt amazing. Xotic guitars does a remarkable oil finish on their necks too. I just bought a California Classic XSC-2 from them and hands down the smoothest best feeling neck I've played. If you gig outdoor in the summer the oil finished neck will be your best friend.
I did my les Paul studio lite recently, and sanded it with finer grits til I used a green scrubby to smooth and apply the tru oil. It’s so smooth and 1000% better.
I actually had lee @ gmw take the clear coat off of both of my PRS necks he did work on and oil them up. there are no issues with doing it and the oil will soak into the wood to a point. just clean the excess off and get back to playing !
just realized you said Danish oil. i'm not sure if that's the same as the oil he uses or not. oops
The trick, AFAICR, is to sand when dry between each application. No need for a "thick-coat" finish. This way, I've found, it seems to soak in better and "harden" the wood just a mm or two in.
