People can, however, do whatever they want. I install a 2 1/2" pin on single string notes , as I said and 2 3/8" on the rest. Reason being the tension and width of the coil. The larger diameter single string core wire can leave a lesser amount of pin in the block if you keep the bottom of the coil off the plate consistent with the treble. In general, the single strings' pins become loose before the other pins (YMMV), so this extra length gives them the edge they need. I do this on new blocks too. Mic'ing the pins helps for even torque too, with the narrower diameters in the treble. There can be four or five different sizes of pins within a set; that's .001" or .002" either side of the spec diameter. I discard the out-of-round ones. -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
