Update: Checked intonation with two different tuners and all seems good there. I was going to lay down a test track by plucking the individual strings and put a tuner on those to compare, but after tonight's attempt that was the least of my worries - had wicked hum in the line, no matter what I did, (changing cables, changing inputs, introducing DI box), plus..couldn't get a strong signal input, (no results/waveforms). So I quit, and just played the **** guitar..
Guess I should start a new thread on the above......
