the tim shaws I had in an '81 les paul were VERY low output (lower than a mule)
stormy mondays should sound similar
if you want a bigger but still soft tone, with more sustain and midrange push, the black dog is amazing
but concerning the antiquities, if you use them a lot live, the sweat might get something shorted indeed
I had this problem with an extremely aged dimarzio PAF from late 70's that came stock in my greco lp
the bridge pickup is completely brown looking, has very low volume and sounds a lot brighter than the neck pickup (the pickups are exactly the same... 7.5k, and short alnico 5 magnet, like a gibson t-top)
it works fine, no strange noises or distortion, but has no DC reading
I replaced them with a black dog in the bridge, cold sweat in the neck (although the neck pickup sounded good)
