Brdige wood, wood

Garland,

Ebony was the choice of wood for Fretboard and bridge followed by Rosewood.
But as you know the world has moved on and there is a growing number of man-made materials that are used now, even Martin and Taylor use them, technically they are better than Ebony and Rosewood, but a lot of the die hard will not accept it.
Anyway to answer your question, by looking and feeling it is very hard to tell, but usually the man-made materials are to perfect when visually inspecting, but now they are adding a very fine grain effect so hard to tell the difference.
They state the man-made materials are more expensive than real wood.

Derick , blues90 , I have persimmon pins in the 00015M and Guild D240E... they have the dots but with fairly small heads... I use them because I like the contrast in color, which is the same reason I use Bob Colosi died bone pins on the 2 slope shoulder guitars, and the hardness is acceptable thought not as hard as ebony...the 00015M came with ebony.

need to be finished better, IMO, but it's not that much trouble to do, so I clean the splinters and sharp edges at the groove...

The Bob Colossi pins are finished really well and being died there are no two alike, which is kinda cool...

Derick , blues90 , the persimmon (Custom Inlay) pins fit just a tad better (as in further in the hole) than did Colosi's pins... but, every guitar I have, or have had, were better than the Ibanez, which were counter sunk so far into the hole I had to use a pocket knife to get under them. One exception was the AMI I have... I had to drive the low E out of the hole it was so tight. I borrowed a reamer from John Miller nad now it's fine.... I expect with a little patience a jeweler rat tail file would work too.

TonyKgull, how do you know their "site" can be trusted? Just curious...

I looked at the Gragh Tech site and they show the traditional pins fit many even Taylor Gibson so on. And they might. The only problem is some acoustics need the groove cut into the skirt like all mine seem to need . I can't tell looking at Taylor's site because they don't show a photo that is detailed enough and certainly why take the chance. But I suppose it Taylor doesn't need that type of slot then these may fit.

There is a reason for the groove through the skirt and those are 1.3T pins. So if you put that type in a Taylor or any other brand that does not need that , I never tried so I can't say if that type of cut would matter. The string will still sit at the top of the pin hole. I still prefer to use the proper pin the company calls for. That groove though the skirt is only for string clearance and the skirt is still the stop. I do know if I used a pin on my guitars that didn't have that groove through the skirt the pin would stop short of seated because the skirt would rest on the string.
