Thanks Gary
Yup, as i posted , someone elsewhere suggested a string change, and specifically Spiro Mediums, as i'm after much more sustain.
The current strings are seated ok, the silk windings are also behaving, and as i stated, throwing the Pizz / Arco switch really sorted the uneven volume,
so i dont see a prob with the piezo.
The dead sustain still remained , however.
Just gotta stump up the coin for a set of T.I Spiros. £144 - ouch ! I suppose i could sell the D'addario Orchestras, though i'm not sure who would buy.
Most people seem to keep their strings, and at the prices, i dont blame them
