Mine is awesome. 3 P-90s are perfect for the Bass VI. It's heavy, but it's worth it. I dominate the range from typical bass into baritone, but without sounding like annoying modern bass wankers. Upper register chords and arpeggios combined with a trem... it's pure sex. It *can* be used as a standard bass, but I find a Morphine-esque use for it. I also find myself going after Sonic Youth type grooves with it. I play it through tubes, for sure.
I'm surprised that annoying trendy kids who think they just discovered fire all on their own aren't swarming for these. I've found mine to be a great creative tool.
