I would have thought that it would have been much quicker NOT to have to produce two perfectly mating flat surfaces - an obvious source of technical difficulty - so for the aftermarket luthier it ought to be quicker and easier fitting an undersaddle to use a 6-piece saddle both to get string height correct and to get uniform pressure on (and hence even string respoonse from) the undersaddle.

Is it usual when fitting an undersaddle to deepen the slot, or to reduce the height of the saddle? If the former, how is the base of the slot made even? Does it involve a precision router? All thinks seem to point to the 6-piece.

I have successfully fitted a Shadow which comes as a unit complete with brass or similar holder and 6 little white bits, and it sounds really good. I have never got as good a result from a one piece with an undersaddle.

Does anyone still make a 6-piece power saddle at a reasonable price?

THe Baggs price above is way over the top.
