Lowering action on a Casino


Recommended Posts

I am curious as to how to lower the action on my Casino. Is it best done with a truss rod adjustment, and if so, do I need to take the strings off to adjust it?

It depends on the the amount of relief the neck already has, the best way to check it would be to use a metal/aluminum straight edge to check it, failing that you can use the strings themselves as a straight edge of sorts, fret at the first fret and the fret where the neck joins the body +1 (usually about the 17th), there should be a clearance gap about the thickness of a business card between the bottom of the strings and the top of the fret at the halfway point (usually about the 8th or 9th). I like to have my necks dead straight (using a straight edge) when there's no string tension, then when you tension the strings this will introduce a small amount of relief naturally. Info on doing truss-rod adjustments and setups is in the DIY thread pinned to the top of the Epi Lounge.

EDIT: There's no need to take the strings off to do a truss-rod adjustment, but they must be untensioned.

I would try adjusting the bridge height first.


I agree! your Tune-o-matic bridge has a post on each side with a slot for

a screwdriver. Turning it to the right will lower the bridge, even with the

strings at pitch. Just have get the string height correct.


A standard string height is measured from the top of the 12th fret to the bottom

of the Low E and Hi E string. Usually 5/64ths for the Low E and 4/64ths for the

High E. Hold the guitar in playing position when measuring so gravity doesn't add

any pull-down to the headstock. Then adjust each side of the bridge to match those

measurements. I set mine just slightly lower, as I like a low action - 4/64ths Low E,

and 4/64ths (occasionally 3/64ths) Hi E.


Of course, having a decently straight neck is a Pre-adjustment requirement. Having just

a little "relief" or frontbow is perfectly acceptable, and is preferred by many players.

Having backbow is not acceptable, and low action will give you massive fretbuzz if this is

the case.


Not knowing the condition of the neck on your git, just do as RaSTuS suggests - from the bout end

just look down the neck to the nut. Should look pretty straight, maybe even a gentle upward curve

at the end. After lowering or raising the bridge, you'll re-tune, and may have to readjust the intonation.


Adjusting the action with the Truss Rod is like pulling the knobs off your git with a CROWBAR.

End result is same, but NOT RECOMMENDED under normal circumstances.


Just keep us updated as to what you see, and ask any questions BEFORE you do anything if needed!

+1 on the bridge comments.


I lowered the action on my Casino until it buzzed, then backed it off until it no longer buzzed.


To back it off, I loosened the strings, gave it a half turn and re-tuned. (Repeat if necessary).


It plays like a dream.

I like the Dave Hunter approach where you get the Trod set properly, check that the nut depth is correct, over raise the bridge and then lower it until the guitar is playable. Tone wise this approach has worked best for me.

That's how I like to do it too, except the last step, I lower the bridge until I just get fret buzz, then raise it a touch. This ensures the action is as low as possible.
