My first bass was pristine. However, my first guitar which was a kay strat got 3 humbuckers, two of which had indivudual series / paralel, coil tap and phase and overall series paralel and phase switches, 9 switches overall, and a badly put in termelo (as I didn't know how the tremelo worked until Melvyn Hiscock had pointed out the errors of my ways. So when I fixed that the front went through to the back. Was a great guitar but it looked a bit of a state and some switch combinations were less than useful!
