Actually, though I don't take issue with 'spaw, I assume what you are driving at is--can the specific differences that come standard in one brand make a better player out of your average run-of-the-mill player (not can a good player make a bad guitar sound good). The answer is an emphatic probably. Case in point. Larrivee has a wider, less radiused neck standard. As a finger-style player I find myself making far fewer extraneous left-hand mutes on a Larrivee. In that way it makes me a "better player". The reason it's not necessarily true is that almost all the major manufacturers are aware of the variations we look for and offer them on one model or another--it's just a maze to figure out what model has what. For instance, if you favor short-scale because of the comfort and accuracy of a short reach/straight attack in first position, you'd have to make yourself aware of f'rinstance, Martin's 000 as opposed to 0M (same body/woods etc--different neck).--blow hard, John
