With the flats on, this is an old school monster with plenty of thump. I've now put a set of the same flats on my Precision and I'm now sorted for thumpiness, so I put some fresh rounds on this SG to try. Sounds like an active jazz on steroids, really meaty with the low mids boosted on the on-board EQ, with tons of sizzling top end. Although they look like old mudbuckers, these Darkstars are single coils with a really detailed and natural sound.
Although it's a lovely bass, my main player is still the Precision, and this is an expensive bass for me to have lying around as a backup so I'm afraid it must go. May trade for a decent Fender P also!
