Re: 1 HB , 1 Volume , Parallel only wiring...no series?
Yes. What you need to do is find out what the different wire colours mean. For Duncan, the green is the beginning of the screw coil, red is the finish. Black is the beginning of the stud coil, white is the finish.
So for parallel you need to solder the white to the green ( the finish of one coil to the start of the other), use red as ground and black as hot. Then get ready for some seriously thin, trebly tone.
