So I bought my first gypsy guitar about 9 months ago - a maple 250M.... loud, brash a little ringing which I learned to control by muting, or use for effect pretty quickly. In short - I LOVED this guitar and I have been playing 50 years and have three Gibsons (175, SG and J-45)…. the setup was magnificent. I had to move to the east coast and could only take a few guitars.... I sold the 250M. BIG MISTAKE.
I found another on Ebay, 2005, with a hairline crack from the pickguard being put on when the humidity had swelled the guitar quite a bit, and when the humidity dropped, the pick guard pulled the wood outside of its area. It was removed by previous owner. No problem, the thing sounds great, and I can live with that.
The neck had quite a bow to it, I adjusted the truss rod to flatten it out - pretty close. The Bridge is the issue. It has one of those old Gitane railroad tie bridges and it has the E string (both sides) at 5+ mm above the 12th fret.
Given my arthritic and painful trapezium (end of thumb bone), I need to get the action down to around 3mm on the low E and 2.4mm on the high E. As it is now, the arpeggios die out on the way up the scale as the string distance increases and my hand doesn't have enough strength anymore to compensate for such high action.
I saw some advice on this forum about lowering action by filing the top of the bridge. My question is, is that too deep a cut to be making on the string slots? I want to be sure I don't sink the string into the slot too deep that it affects it... I understand the slot should be about half a string height. So I guess that means a wide channel groove to achieve those dynamics. Seems like it could be a little sketchy.
Question: Should I attempt this or try a different bridge... I am unsure about bridge shopping. Height, brand etc. Any suggestions. This guitar will have to do until spring when I can look at something European. ($$$). But I know the 250M can be set up right because I had one that played like an SG and still was ripping loud!

So, no matter, lets have a look.....well the neck looked too flat, possibly even a slight back bow, so first thing was to back off the truss rod a little. Then retune, check again and a final small adjustment got the neck ok, but the bridge had been sanded down too low. So, a few shims of a spare piece of veneer brought it up to a sensible 2.75mm action and now it is all playing great.
I mention all of that only to say that many of us have come across some odd setup problems, and often different problems with different causes, but usually nothing to be afraid of. If a human did it, another human can undo it.
For yours, I would echo the suggestion above to start by sanding the feet of the bridge. On this guitar because there is no curve to the top it is easy to do, but go gently. Slacken off strings enough to be able to turn the bridge on its side and remove it, sand the feet on a piece of 120 paper on a flat surface being sure to apply even pressure to both ends. Put back under strings and just by tightening the top and bottom E strings a little you will be able to see how the action measures at the 12th fret. If needed, sand some more, possibly finishing with 180 or 240 grit just to give a smoother finish.
In theory if you want to lower the action from 5 to 3 you would need to remove 4mm to achieve lowering by 2 but the geometry doesn't quite work that way so take it easy. Best to do a little at a time rather than take too much off and then have to shim it back.
You certainly do not want to be filing deeper string slots, that could cause a lot of other problems with tone, intonation and muting.
The top of my DG-250M is absolutely flat in both directions.
Interestingly it takes a very slight concave dip (probably less than 0.5mm) in the bridge area when tuned up. This can only be due to string tension pushing down on it but it certainly is no problem.
(BTW -I have checked inside with the inspection camera, the braces are all fine and there are no cracks and it is not getting any worse.)
My suggestion to finish with a finer grade was simply to remove any rougher marks from the 120 and at the same time ensuring a cleaner surface, and would only take a few seconds but yes, not entirely necessary.
