I'm researching buying an OM instrument there is plenty of choice on the internet but not much scope for trying things out in shops. To narrow things down a bit can someone summarise the effect on tone and volume of (a) archtop vs flat-top (b) guitar-type fixed bridge vs floating (c) f-holes vs round holes (or oval and D-holes for that matter).
I'm really just after a summary of "received wisdom" on this, I realise there are always exceptions to the rule and a good luthier can produce instruments that break the rules.
Thanks
