Here is one that I'm sure will stir up lots of discussion/argument, but I'm really interested in people's opinions. There are some really good custom bass builders out there (Sadowsky, Lull just to name a few) - whose main products are knockoffs (but improvements) of Fenders. But not many of the "pros" (people whose only job is playing music) play them. Why? Is it because: 1. They are all playing vintage Fender/Music Man/etc. that are rare and expensive - not what is for sale new? 2. They have techs who customize their axes to the point where they are closer to the designer basses than the off-the-shelf basses? 3. In the studio they are not playing the same basses they say the are, and are playing live, due to deals with the manufacturers (lying is SUCH an ugly word)? 4. Or are those who spend $2000 and up on a new, yet basic, 4-string bass not getting the bang for the buck they think they are? OK - everybody chime in.
