I just have this cheap ass woods acoustic that's been laying around saddle-less and string less and I've been looking for a replacement. What's the difference between a 1/8 saddle and a 3/32?
I'm sure it's the measurement of the saddle perpendicular to the strings, not sure though...
I do know that if it has an under-saddle pick-up then you will want your saddle to be loose, if not you want a good tight fit. Also any saddle you get is gonna need some adjustment, they aren't really a drop in kinda item.

Hope that helps,

About 1/32".

Nicely played. To TS, it's just the thickness of the saddle, in inches.
