<<Then why talk about moving the pins at all--if it confused me--it would confuse a client.>> Never had a "confused" client yet; I simply tell them that After the intial pitch change (large pins movements which increase tension the most and will effect previously tuned notes) only the smallest adjustments are then neccessary in the fine tuning stage that will not change previously tuned notes.

Date: Wed, 21 Dec 2005 08:37:55 Hi Terry, Then why talk about moving the pins at all--if it confused me--it would confuse a client. By the way I think the pins flagpole in the block under tension and do contribute in that fashion to instability. As far as DC systems go I'm waiting longer and longer--3 months to six months if I can--and find that some changes are still happening after a year.
