EDP sync and sale/resale

["Gary Lehmann" <hqr@cox.net>]

Claude and Luis were discussing the Echoplex being available again in the
near future (huzzah) and sync issues--
I sold one of my two Gibsons a month ago to help with cash flow, and never
had a huge issue with Brother sync not working--
I hope to acquire another EDP when they are plentiful, maybe get a (ahem) 
Al
Jolson model for the novelty--
What did Claude mean about sync?
I know there are issues sometimes with matching the crystals on units--but 
I
never noticed a problem . . .
