The SimS PUPs are lovely, as are the basses themselves. Took me a long time to appreciate how to use the PUPs, easy to forget that when you play a Precision you address is differently to how you address a Jazz or a 'Ray, and I've tended to use dead flats on Precisions, zingy rounds on Jazzes and lively flats on 'Rays over the years, plus of course the baked-in tone in a 'Ray circuit is very different to standard active Jazz circuits. I started out with an Enfield FL where so much of the tone is in the fingers, moved to fretted where the differences were more tangible, and now with both I see the PUP switching as pretty awesome bunch of preset options that may not replicate the three basses 100% but provide options way above what you'd get from any single preamp (and of course on both instruments I get to to choose both PUP and preamp settings).
