All PreAmp settings are the same in terms of EQ and gain.
Difference in volume comes from the different outputs of the pickups!

Have fun with it!

P.S. For all eagle eyed viewers:
I had a camera flaw when filming the Fallout Tribute parallel mode slap segment. The tone is the parallel mode, but the picture comes from the singlecoil mode. So don't wonder about the switch ;)
