I hear you - I too have been skeptical of digital vs analog and your insights have reinforced that skepticism. The reaching for "better" based on "newer" always needs to be entered cautiously. As with tube vs SS in amps - after all these years they are just starting to create a hybrid blend that is dependable with character.
You could get an affordable neck to replace the crappy Rogue neck and still end up with a playable instrument. What scale are you after?
I well remember when anything that was digital absolutely had to be better. That was the late '80's / '90's and early 2000's. People were touting "digital speakers". I guess they outputted ones and zeroes. It's all cyclical. I found an old Dynaco preamp and power amp with a Thorens turntable on the curb decades ago. It was worthless at the time. I can get at least $2,000 for the set now on "the bay" that is if I wanted to sell it, which I don't.
Yeah, I might get an affordable neck if the "dewarping" technique doesn't work. When I took it off the bench today it was convex. Unfortunately (fortunately) I'm bogged down with organ work so that's all the "basswork" did today. But I make money with organwork - so I can buy bass parts, amp parts, basses, picks, strings, etc.
About a decade or so ago I made a nice body out of Holly, which I lumbered myself - it's a long story, 120 year old holly trees being cut down for McMansions. I had intended to build a 5 string but never finished it. It's raw, no neck cutout or cutouts for pickups or electronics. I didn't have a milling machine at the time and the project fell by the wayside along with many other projects. Stewmack and Carvin were my sources for necks and other parts. I'd intended to get a "paddle" neck and cut the machine head on the bandsaw to a unique design. But that was then. Stewmack seems overpriced and I'm wondering what the other builders use for a source of necks. I could make one from scratch, and really want to someday, but time is the problem. Setup is the biggie. I more or less know how to make a neck cutting jig and can get just about any type of timber but it's just so time consuming and I have four different professional projects going and can't justify taking time away from them. Who sells decent, inexpensive necks and other parts?
