I think there are too many which seems to be done purely for marketing purposes rather than giving the consumer maximum choice - unless there is a new product launch (even as a revamped current model) the music mags will not review/reature/talk about it and, the consumer won't have it thrust in their face.
I understand that most people think it great to have the choice, but typically choice only appears on the 'net as most stores will only stock a limited selection of what is available. Then there is the added confusion of all the Fender clones - whether they be high quality clones/updates or lower priced copies. When I started playing in the mid seventies my mind was 'bogled' by seeing a couple of variants of a Fender P (maple and rosewood 'boards), two Fender Jazzes, one with a 'bullet' truss rod, several copies from Aria/Ibanez - upper priced copies, to Sakai - lower priced copies, and then there was a Ric with checker board binding next to a Ripper bass............................now, what was that Mary Hopkins song?
