Thanks for the feedback, chaps, much appreciated.
Stingrayfan, that sounds excellent. What interface do you use, out of interest? Do you apply compression in GB itself, or beforehand via a pedal in chain? I used to own a BB414: really fast neck on those basses - I even got close to nailing Rhythm Stick!
Good point re: strings too - I used some old flats on my recording and they obviously don't jump out of the mix. I'm going to stick some nickel rounds on and compare.
