[PTL]

I am trying to help someone figure out how much to increase the height of a saddle and need a particular kind of shim.

The steel string guitar in question plays perfectly on the three treble strings. But the three lower string buzzes due to a saddle that is too low, getting progressively worse towards the low E. The low E is buzzing badly from the 1st to 12th fret so that.

So I'm looking for a shim that is a perfect triangle where it is feathery paper thin on the treble end and goes up to perhaps 2mm taller on the low E end. This is to see if 2mm is enough of an increase.

Does anyone supply a shim like that? For you guitar tech, this is probably laughably trivial task but while I can get shims that evenly thick across, I am not sure how to cut something this thin into a precise triangle from paper thin to 2mm height.

Thanks in advance for any help.
