<html> PianoTek has a nice little upright voicing tool. Sometimes for extra hard vertical hammers I find it's easier to use one needle from the sides.

I don't like the idea of swinging the action back and forth to needle, listen, needle, listen...etc.                The great idea is to dismantle the voicing tool, saw off the 1" or so handle insert thereby having just the needle (cartridge?) head in hand so that I can work quickly with the upright action in place. Is this a good idea?  Julia Gottchall, Reading, PA </blockquote></html>
