Hi all
I recently bought an old Streamer std German made Warwick with a pair of MEC vintage style HB PUs. I was looking for a double buck but this came up super cheap so i have refinished and done some work on it. Pics will come at some point!! Each PU has a red/green/white/black and braid wires. My intention is to fit an EMG preamp (old BTS) that i have knocking around. So if all is well i will end up with vol/vol/bass/treble.
So questions. Can I add 2 3 pole switches like the double buck and wire the same so i can expand the tone by running PU's in series /parallel/etc?? If so can anyone supply me with a double buck wiring diagram as I am struggling to find one. If this can't be done can someone give me a wiring diagram for wiring it straight to the preamp wiring. I have found a wiring diagram from EMG.. (it is the old BTS system with a small board)..i understand how to solder the BTS to a JP config ( that's what I had before) but with so many wires coming from the PU's...i am finding it a bit confusing as to which wire would go where...
I hope this makes sense and is achievable.. . I am hoping as always that someone here can help.
Cheers all.

If it is any help I recently did excatly the same thing(I have added two DPDT (on-on-on) switches) with my '93 Streamer broadneck. Mine has bart soapbars but the wiring scheme and low output sounds much the same as your situation.
You may find the info in the pdf below useful in terms of switiching/wiring option - starts on page 2.
