I bought a new 55-02 last December. Initially, I was awe-struck with the look, feel and quality of this instrument - amazing! In fact, after one week, I thought I had found my "grail" bass! Except for one little detail....the sound. Meek, mild, sorta....well, almost wimpy.
Try as I might, I couldn't get there...by itself, it wasn't bad. With my band, however, this baby would get covered up faster than I could believe. I wound up, on several occasions, sticking my ear about 4' away from my 200W amp just to hear myself.
Tried everything - changed the settings on the toggle switch in the electronics compartment, changed strings, messed with the EQ settings on the amp - some of these actions helped but still didn't get me where I wanted to be.
Finally, I traded it, to a fellow TB'er, for a G&L L2500. All I can say is, ZOWIE! NOTHING covers this baby up - truly an amazing sound. Best I've ever heard from a bass (although my Yammie BB415 comes REAL close)!
I realize this post might seem like a diss of the 55-02, but really it isn't meant to be. Just another example of "different strokes for different folks". The TB'er that got my 55-02 really seems to like it, and I'm undoubtedly in the minority here with respect to how the 55-02 sound is perceived. But would I turn back the clock and "undo" the trade if I were able? Not a chance. I felt same way till I tweaked the pre amp by removing cover . You stated you tried everything yet didn't mention adjusting lh3 pre amp inside the bass lmao
