In the quest for the perfect bass, what would be a good choice for a 4 string to nail "old school" sounds like Fender P, G&L L2000, Jazz, MM etc. Some might say, why not use Fender, G&L etc? Answer - 'cos I want to get something custom built. No slapping, all fingerstyle for: blues, R&B, Motown and Classic Rock. OK it may not be all in one bass but what gets closest in high-end basses out there? Which builder, woods, p/u, might work? Thanks for your positive input.
