They don't all sound like that. My super won't sound like that ever. His has a definite scoop to his sound and strong highs. Mine has more lows and mids and a lot smoother treble with both humbuckers on. Much more full sounding for finger style. On the flip side it gets a whole lot more slappy with both coil taps in single coil mode. Mine is ash, maple/rosewood.
There's a good video floating around online of someone comparing a handfull of 535's with different wood combos back to back. They all sound similar but not the same.
I saw a video with Andrew Gouche a/b'ing MTD basses with diff. wood combos.
