I'm pretty much an electric player who's getting used to playing acoustic. I've got a Yamaha FGX-413SC, a nice guitar for about $400, and I use light gauge strings. I plan to eventually change the saddle with Tusq, so I've been sanding down the saddle little by little, seeing how low I can get it. I figure if I take it too far, I'll start over with the Tusq saddle, and a better idea of how low I can go. I've been sanding it down, following the contour of the bridge, and I've got it pretty comfortable. The saddle has got about 1.5x the thickness of my bass string sticking above the bridge itself. I don't have any high-precision rulers, so that's my frame of reference. There's no buzzes or anything, but I'm wondering how much further down I can go. I like really easy action. Any tips, hints, tricks, etc.?
