I ve been contacted fernandes 1 week ago and they reply this:
Unfortunately we don’t have a diagram of the wiring for the specific system you are attempting to install. In order to separate the driver humbucking signal from the sustainer you will need an additional switch to isolate the mini humbucker.
nothing at manic music
vai use a fernandes sustainer on : flo, flo 2 ,fretless of his tripleneck jem , and the new bad h (the mirror one)
I ve picts of each closiest to see "sustainer tm"
