Anybody use these pickups besides already having them come stock in a Geddy, Custom, or other Jazz bass? I am considering these for a Warwick Corvette with a "fresh" Bart NTBT preamp to mate with. If so, how is the output? Punch? Hum? "Burpiness" of the bridge pup? Surprisingly, the stock MEC's are pretty quiet and tight, but me Beano wore off....and I'm a g.a.s.'n...... Thanks!!
