Without any truss rod or string tension, the neck relief is .06". Miles better than when I first started working on it. But with the truss rod tight (but not bottomed, but very close) the neck relief is .02" WITHOUT any string tension. With string tension, it's about 1/16". Still way too much.
I made a couple of truss rod nut washers from the washers I bought for vintage Yamaha's. The OD is .34", but the hole in the neck is .31". I sanded the OD on the belt sander. It's tough since they heat up quickly. I'd sand a little on one, quickly put it down, sand the other one, etc. I figured they'd be a pain to get on the truss rod since it's so far in the hole, but it only took 3 tries total.
I back bowed the neck again, about 3/8" at the nut, with no string tension. I'll leave it for another day before trying the truss rod again. If I can get it to stay in a slight back bow I'll be happy. I'll probably leave it like that for another day before adding string tension.
Well, I removed the back bow and with the truss rod loose the neck relief was about 1/8". Not bad. I tightened the truss rod and got the neck flat. I tuned it up and cranked the truss rod some more. There's still a little maybe 1/8" travel left. I got it to about .02" neck relief. I'll take that vs continuing to crank on the truss rod. I expect it will creep up a bit over the next few days. There's a wicked buzz at the 14th fret because there's literally a DENT in the G string! So far so good!!
I ended up buying a P-Bass copy neck from a guy on eBay for $26. He only lives 20 minutes away so I arranged to pick it up in person. I had to initially pay $17 for the shipping and he refunded it.
A couple of days later I finally took a closer look at the neck I bought to find the hole pattern and end were different than the P-Bass. Oh well, I guess I can plug & redrill the holes and sand the end to fit the pocket. AND I find the 4th fret is much lower than the rest. Of well, I bought it.
Then in an odd turn of events, I get an email from someone asking if I got the shipping refund. I replied yes and asked who this was. The reply was it's the guy I bought the neck from. I replied about it not fitting and the 4th fret being low. He offered a 2018 P-Bass neck for $45.
Not wanting to sink another $45 into this project I checked my neck again and find the straight edge hits on the first & last frets with an approx. .020" gap in the middle, even though the neck relief from the 1st to the 15th was OK. I find the neck is slightly bent where it meets the body. Not wanting to be a disgrace to my "profession" I removed the strings and sanded and recrowned the last few frets (mostly the last one), and also steel wooled all the frets and oiled the fretboard. It's somewhat better.
Then I find he's refunded the $26 I paid for the neck! He said I could keep it for the hardware, but also asked what I'd like to do about the P-Bass neck he had. I said he didn't have to do that, and I told him what I had done and would stick with my neck. Then he sent a cryptic reply "Hmmm, what to do now. I did give you a refund for it already.". To which I replied "Did you want $45 AFTER refunding the $26?? I'm confused.".
CTGull, Sounds to me like the guy figured you'd buy the other neck if he gave you the first one for free and that he would have been happy unloading both for 45 bucks instead of just one for 26 bucks and being stuck with the other. He probably did not figure you'd fix the one you got and not want the other one.
This is what happens when people assume. LOL.
===================================== One Alvarez in the hand is worth two Taylors and a Martin in the guitar store!
I'm still trying to clarify. I offered to buy the P-Bass neck for $45, I just wasn't sure if he originally meant he wanted $45 on top of the $26 I already spent. $45 for a 2018 Squier P-Bass neck is pretty good. And we could meet semi-local. Although it's pouring here on and off.
A couple of observations of playing (or attempting) this bass. The length of the neck is very dangerous in my work area!! AND, I seem to be adjusting to the longer scale length quite easily. I made up a pattern and after a couple of tries, I was able to play it without looking 4 times straight without a mistake. I was afraid the long scale, vs. the 6 string guitar, would mess me up.
I started attempting to transcribe YYNOT's Etheria using TuxGuitar TAB program at 10pm last night. It doesn't do the transcribing, I have to do that by ear. It allows you to make the tabulature, AND it has a playback function so I can hear if I got it right. It ain't easy!!! I think I got the first 2 measures done. At this pace I should be done by Easter, next year!!
This is so odd!!! I've been terrified of attempting solo's on the 6 string acoustic guitar. I just can't wrap my head around those 6 close together strings!! The bass doesn't scare me. I'm actually looking forward to learning to play it. I bought the Bass for Dummies book a couple of years ago. Maybe I should get it out and learn some basics.
I passed on the vintage Lotus bass. Cool, but I don't need to start collecting basses!! I need to learn how to play them!! All I need is time!
The guy I bought the generic P-Bass neck from refunded the money and we finally met again today. I returned the neck and paid $45 for a 2018 Squier P-Bass neck, plus $10 for a set of tuners. He said he had 3 bass bags but it turns out the biggest bag he had was for a 30" scale bass, about 3-4" too short.
