BTB, Adjustments and Setup

Discussion in 'Hardware, Setup & Repair [BG]' started by basstastic, Nov 15, 2001.

  1. Another question aboot this guitar from the dr. Ordered it mail order, the shop is not walk or reasonably priced public transport distance away.

    So, i noticed the action be too low. Fret buzz on E and B string on 1st and 2nd frets. I need to adjust action, looks scary. (as do the electronics, but i aint gonna touch them) So, how did YOU do it? Diagrams not necessary, step by step guide will do

    Thank Yous Alls Very Muchen

    first, I think this has to be in Setup, JT, Ryan, please move it, ok ?

    Adjusting the Action

    This is a pretty easy step. All you need is an allen wrench. Look at your bridge. You´ll notice that each string is going over one saddle which has two holes. One over the string, one under it. (It´s the same with the Monorail Bridge, I believe).
    Insert the wrench, turn it, and try to get the right direction to raise the height of the saddle a little bit.
    Maybe, you´ll also have to adjust the Truss Rod, but I haven´t done this so much (my bass tech is setting my basses up for me since I am in my new band Abandoned and before that, my bass instructor did it for me).

    I don´t think that the electronics need any adjustment if they don´t sound wired. Just play around with the controls until you´ll find out what the different knobs do.

  3. Buzzing on 1st and second fret could also be a problem with neck relief - I'd check that first.

    Here's how I do it - and there was a great article in last month's Bass Player mag that said a lot of the same stuff but I like my version better ;)

    <b>Stuff you need:</b>

    • A tool to adjust the truss rod. This is usually a pretty fair-sized allen wrench.
    • A capo. A g*itarist might have one - if not, they're fairly cheap at the local music store.
    • A feeler gauge.
    <b>How to do it:</b>
    1. Tune to pitch.
    2. Put the capo on the first fret. With the bass in playing position (so gravity doesn't goober up your measuring), hold down the last fret and measure the distance between the top of the 8th fret and the string. For starters, .010 to .020 inches is good - you can adjust from there if you need to. Someone here said a business card is a great field expedient measure and I think that's a great idea.
    3. Tighten the truss rod to reduce the amount of bow or loosen to increase it. Don't adjust more than 1/4 turn at a time and <b>never</b> force it. If you break a truss rod you'll end up replacing the neck, the whole bass or paying many dollars to have the fingerboard removed and the truss rod fixed.
    Wood doesn't change shape easily or quickly so it's probably a good idea to recheck the neck relief the next day and readjust if necessary.

    Then - you can adjust string height. There was a great article in <b>this</b> month's Bass Player on this. If the neck is within spec I like my strings about 3/32" above the 12th fret on the B (or E) string and about 1/16" above the 12th fret for the G (or C) string.

    Play the bass normally. Most people I know don't pluck strings as hard when the bass is laying on a table in front of you - what sounds just fine on the bench might suck mightily when you get onstage.

    After you're done monkeying around with string height you can check intonation. This is easy with a tuner or a trained ear. I like to tune to pitch before each adjustment but some folks will tell you that's not necessary. Check the 12th fret harmonic against a fretted note on the 12th fret. If the fretted note is sharp, move the string saddle away from the pickups - if it's flat, move it toward the pickups.

    String brand and string gauge both affect neck tension and intonation so if you change strings you may get to do this all over ;)

    hope this helps,

  4. thanks allan, i really appreciate, i'll go and try that
    thanks a lot.

    You will get more of a response for this in Setup, as already stated. It's gone.
  6. * ahem *.. :rolleyes:

    aren't you people forgetting that the Ibanez BTB has 2 trussrods ?

    so if you turn one out of 1 too much or too little, your neck will twist.. making the action / relief /etc a pain in the a$$ !

    Better bring it to a store and let a certified repairman do it.that's what i did with my BTB, and it's a killer now ;)

    How do you replace strings with a Monorail bridge? Not a string through body monorail bridge either.
