Post subject:  Compensated Bridge on my Samick

Just put a Grover compensated bridge on the Samick 5-string that I use backless. it has the tone I want and decent action, but playing "A" on the second fret of the third string was always "iffy," usually quite sharp. Playing B on the fourth fret of the third string, then playing B open on the second string was anything BUT unison. This was with the first and fourth string in perfect intonation.

I ordered from Elderly.com, because I ordered several other items at the same time that weren't available anywhere else. Service was quick and the order was correct. That said, if you want to see the thing on Amazon, click this link: http://www.amazon.com/gp/product/B003B0 ... FFOTNOVTZD

I ordered a 5/8"-high bridge. although I had a 1/2" before, because the neck could stand to be cranked back a bit anyway. I used the turnbuckle to reset the angle of the neck so I could try the thing out before I got out the allen wrenches, and it worked pretty well. The Grover did not solve the problem completely, but it helped quite a bit. I play a LOT of songs using open G and related chords, so this is a good thing. I'll update after I readjust the neck properly.

For the uninitiated, the third string on many 5-string banjos can be perfectly in tune open (unfretted) and go sharp when you fret it. A compensated bridge has a "bump out" under the third string that makes the length of the string a tad shorter than the rest of the string lengths. This is enough of a change to fix the problem on most banjos. By the way, I've been told that the sharp A note on the third string was because I was doing something wrong. But the problem wasn't as noticeable on the other three 5-strings I've owned from three different manufacturers (from Kay to Deering, if that tells you anything). It WAS noticeable on a "$1200" banjo I test-drove once, so I'm not open to the suggestion that it only affects cheapies.

One expert told me I was just fretting that particular string too hard and if I had a lighter touch, it wouldn't be a problem. But I fret the other strings just as hard and they don't go sharp. Besides, I also play 12-string guitar, so I'll never have a light touch.

At any rate, it wasn't a very expensive experiment, and it seem to have paid off very well.

Follow-up: Today I got out the allen wrench and screwdriver and adjusted the Samick's neck, cranking it back a little. If you've read my article on that (and my other banjos and guitars etc.), you may recall that the neck was a TINY bit concave between the nut and the fifth fret. Not enough to cause any problems, but I was hoping that if I had a higher bridge, I could crank it back a little farther without creating fret buzz somewhere further down the neck. Turns out I could. I had used the turnbuckle on the single coordinator rod to bring the neck back overall when I first installed the bridge. Today, I used the neck adjustment rod to crank the neck back. Now it's straighter. But there was a tiny bit of fret buzz at the first fret. So I loosened the turnbuckle a turn, and the fret buzz disappeared. I may have to tweak it again in a couple days, but for now the action on this is the best it's ever been.

That said, it may be the outrageous humidity, but I DO feel that the banjo is a bit less "bright" and responsive than it usually is. Maybe the folks that thought the bridge was too bulky were right. That said, I ran through songs in G, D and A, and all of them sounded better than they had before. So it's a trade-off I can live with for now. I came close to blistering my fingertips today, trying different things, so that's the end of my report for now. :-)
