Martin Dreadnought Jr Sapele

luccman,

Last year I owned the Martin Dreadnought Junior, but the spruce model.
Found it to be a great Guitar, enjoyed playing it, but within a few weeks it needed a neck reset, so the guitar shop that I bought it from let me have any guitar that was the same value, I picked a different brand of Guitar. 😀

luccman,

No I don't think it makes much difference, maybe a little bit, but it will make your guitar look better, and may make you feel like playing it even more.

luccman,
As CTGull as said, different strings will make a difference to the tone / sound of your guitar, also if you are playing with a pick, try a different pick, different material and thickness of pick will give you a different tone. 😀

luccman , one difference I find a change from plastic pins does is make string change time better. The ball ends can really deform the slots in the plastic pins, and make them hard to get loose. With ebony or other hard materials like bone (brass would be the same I would think) the ball end comes loose more easily when the de-tensioned string is pushed toward the pin.

 That reason alone justifies replacing plastic pins in my view - especially if you change uncoated strings about once a month like I do.....

I have never changed the pins in any guitar that I have had.
On the rair occasion when doing a string change, and tensioning the strings to pitch had the pin fly out hit the back wall, rebound of the ceiling, then disappear, only to find the little bugger about an hour later, after searching on me hands and knees.
Now I put a piece of cloth over the bridge pins, untill I have the strings up to pitch, just incase. 😀

RobertW,

That's how I know the pin is not set correctly, but on the odd occasion that's the only way you know it's not set correctly.
