a treble bleed is not redundant with 50s wiring. you preserve much more high end with a treble bleed, well... depending on values, than with 50s wiring. if i was going to use a treble bleed, i might stick with modern wiring though to minimize the odd interaction between volume and tone controls
with active pups, you dont typically lose high end when you roll down the volume since they are low impedance. you could probably wire a treble bleed in there, but i would have no idea what values to use
