I get the impression everyone now believes that most preamps are rubbish, and you have to make sure you get a special one to record a guitar with a 57 or other dynamic. Are we really designing preamps worse than those available in the 70s when home recording took off. If any name manufacturer has a product being sold that can't do this basic and simple thing somebody should create a list. Preamps sensitive and quiet that can record a flea fart are one thing, but recording a guitar, even a quiet acoustic, isn't really beyond most, is it?
Not sure it matters, but if the singer has dreadful technique and covers the rear grill slot on a 57, it sounds dreadful which you cannot do on a 58. The little foam windshields for 57s can, if out on and taped with a bit of air space, stop some singers getting too close, as they're quite stiff and prickly!
