Posted this on acoustic guitar forum already..
Need some advice about the bridge/lowering action/intonation - it looks a bit bizarre to me.... SEE PICS


Just been to pick up a new guitar, well it's really old but new to me!.
Won it on a well known auction site for a VERY low amount...

So it's a Kawai Acoustic (no.631 to be exact).

From researching it up.. japanese made - seems to be parent company of teisco..
Could've been made from late 60's to late 70's..

Anyway here are some pics and some advice is needed.














Problems:
The action is UNPLAYABLE...
From looking at the pics of the bridge i suspect a new saddle/bridge has been fitted at some point.. making the action unbearably high and really awkward...

The tuners are ancient, but usable i guess..


From strumming a few open chords on it, it sounds pretty good.. but there is buzzing and all sorts of intonation problems..


With the bridge, due to the tailpiece, is there any way i can lower the action and so forth?


Oh and.. i'm living at home in the box room for the summer so ignore the paint hahaha

Hmm...

That neck looks bowed too. Luckily it appears to have an easily accessible truss rod.

As for the bridge and so on, pass. Sorry, I'm an electric guy. I'll leave you to the acoustic-users who know.

yeh the neck looks bowed slightly around the 5th fret..

if i adjust the truss will it give me some benefit?

Check if the neck is straight (it does seem to bow slightly) and adjust the truss rod if necessary. Make sure you loosen the strings first and only twist it in very small increments.

If the action is still too high then you should be able to slide the saddle right off and file it down a bit, I'm not sure if it will effect the intonation though.. I'd wait for a second opinion on that bit.

*edit*
Ahh! Ninja'd! My fault for being slow.

Yup. Loosen it slightly and slowly. Turn the rod clockwise for about a eighth- or quarter-turn, leave it alone for a couple of minutes (giving it time to adjust), then check the neck again. Repeat until the neck is so straight it would make Chuck Norris look gay.

There isn't really a lot of technique to it, but this page is pretty helpful if any massic unforseen problems turn up.

First time I've ninja'd someone.

Edit: Oops, clockwise.

Yes, the guitar should come with one.

CLOCKWISE, sorry.

Edit: If it didn't come with one, check the key-slot-adjuster-thing to see what kind of wrench you'll need, and if you don't have one lying around then go out and buy it. You should be able to get one from a hardware store or, failing that, a guitar shop.

Sorry, either UG or my computer is currently being a bitch.

nope didn't come with anything, sort of came out of someone's loft by the look of it, very cheap though..

as you can see the action is extremely high, will a few turns really make it playable?
#10
the truss rod should normally be located just under the hole in the body right?

nothing there..

how would i adjust this?!


Has that slipped down or something?

If it has, then "Oh, fuck" is the appropriate course of action.

If not (it is kind of hard to see in that picture), then follow the above instructions.

Sorry, wasn't paying attention.

What you're doing is trying to straighten out the neck by putting more pressure on it. A straighter neck will certainly improve the action, though you'll probably need to fiddle about with the bridge before it's perfect.

However,

A few turns? Hell, be careful with that thing. A few eighth- or quarter turns will help, but you certainly don't want to go overboard with it.

Take your time. It's a pretty straight-forward operation and one that is often over-hyped in terms of difficulty, but getting it wrong can damage the neck badly. Turning it round completely doo-lally without a care in the world definitely counts as getting it wrong.

i really dont know..

i imagined it would be like an allen key.. doesnt seem to be anything...

would taking it to a tech really help?

Allen key goes in, allen key goes round a little bit, allen key comes out.

Check the neck in a couple of minutes and adjust again if it isn't right.

Don't worry, it's a simple operation.

Are you saying your smallest socket is too big to even fit in the slot to get around the adjustment nut?

You may need to get some specialty thin walled sockets.
