I had to do it! We A/B'd my Sadowsky and Eshenbaugh basses. Again, no suprises here. Eshenbaugh: THUNDER - Alder body, Walnut top and back - Maple neck, Rosewood board - Dimarzio Ultra Jazz pups - Aguilar OBP-3 preamp (9 volts) - SR2000 strings - Deep, deep low end - Smooth highs - Scooped sounding (mid freq adjustable) - Sounds more like Marcus Miller's tone than his MM Fender signature bass does. - Fact: If you want to know what this bass sounds like, listen to Marcus Miller's latest album, "Ozell Tapes: The Official Bootleg" - The Eshenbaugh body/design contributes to a low end roar that I have yet to find on any other bass. Sadowsky:LIGHTNING - Alder body - Maple neck, Morado board - Sadowsky (Dimarzio) pups - Sadowsky preamp - Slowound strings - Big fat bottom - Nice mid-bass punch - Smooth, defined mids - Razor-sharp clean highs - The Sadowsky preamp...WOW! Summary: No clear winner here; it all depends on what you like. But if I could take only one bass, it would probably be the Sadowsky because of it's flexibility in the upper frequencies.
