Has anyone tried TB pickups on a Maple bodied bass ?
Gibson has. On the EB 650 hollowbody (which in addition to its maple body had a huge maple sustain block and maple neck). That bass sounded sharp to the point of harsh with them, not an inherently bad sound if one likes aggressive sounding basses, but expectation-defying in a baffling way when it comes to hollowbodies which you imagine to be mellow and largely attackless. On a Grabber, which sounded raucous (and was supposed to sound that way as Gibson's P Bass
Vergeltungswaffe) to begin with, sound and expectation might just match. The TB Plus should have the middish rawness of the old Grabber pups, but with more treble sparkle and a lot more bass ooomph. I always found Grabbers lacking in that latter department. They're loud and abrasive, but don't have the sublow authority of the otherwise more docile (or less overt, if you like, Grabbers do nag a little in sound) Ripper.
