Well, as I said in my previous thread, I felt the action too high when I first played the bass, so I lowered the saddles. The bass is buzzing all over the fingerboard. Another reason to think that the neck is OK. The A, E and B strings buzz more than the G and the D.
I'd like to share the current action measurements with all of you, but I don't know what tool should I use for that and how should it be measured. I mean: From the fingerboard (the wood) to the center of the string? From the edge of the fret (the metal wire) to the "inner edge" of the string? (Hope you understand what I'm trying to say) At the 24th fret? Thank you in advance for your help in this.
And thank you for your comments! That's stuff I've been playing for so many years and still not happy with it. I wrote "Linus And Lucy" in standard notation using Finale exactly as you hear it in my recording, except that this audio example is abbreviated (no repeats). I'm going to work on the tab. It's easy since I already have the Finale file with the notes. BTW, Stu plays this thing a half step lower. I decided to play it in the key of Ab because that's the original key (as recorded by Vince Guaraldi).
Thank you again for all your support and your comments, folks!
Well ill explain it as i was taught, to measure the neck relief (how much it bows) press the A string on the 1stwith your left hand index finger and last fret pressing down the strings with your right hand elbow, the space between the middle fret (yours is 12th
) and the lower part of the string can be measured as the neck relief, the neck relief in my jazz has the thickness of a credit card and the vigier (wich has no truss rod) has a little less.
The quickest way to tell if the right amount of relief is in your neck is to lower the strings. If after lowering the strings, the notes buzz only above the 12th fret, then there's too much bow in the neck. You'll need to tighten the truss rod.
If after you lower the strings, the notes only buzz in the 1st 5 frets then your neck is too straight. You'll need to loosen the truss rod.
If after you lower the strings, the notes buzz all up and down the neck, the neck's fine. Your strings are just too low.
Loosening the truss rod:
You'll need to loosen the A string to move it out of the way.
Important!
Turn the wrench counter-clockwise (in my bassesthe TR works this way) only 1/4.
You should be able to see a difference after a quarter turn. If not, try a little more, but I'd recommend no more than a half a turn per day. Wooden necks require time to "settle in" to truss rod adjustments.
Tightening the truss rod.
Tightening is a little more complicated.
Before you turn the wrench, you need to "help" straighten the neck a little.
This is easiest if you're sitting down.
Stand the bass on the floor.
Put your foot in front of it.
Put your knee behind it.
And carefully push on the front of the headstock.
Then u adjust the string height with the saddle screws and an allen wrench till it stops buzzing considering the curvature of the pickup pole pieces (if it has any).
"Wich tool should i use to measure the string height?" i havent found any yet.
