XBones ABY switch with 180 polarity and ground lift
I am currently running a Radial Xbomes ABY switch to a yba2b tube amp head into a ul2 1x12 NYC style speaker and the other rig is an epifani 502 and a NYC 2x12 with eminence speakers.
My question is the 180 polarity switch. When activated (switch is up) I feel like all my boom goes away and it sounds muffled. Should I use the switch because of other reasons? Something about the speakers going in the same direction or something with phase?
Any help appreciated.
You have discovered what the switch is for. :) All different gain stages (EQ, fx, clean gain, etc.) alter the phase of your signal a little or a lot; and some of them flip the phase completely. When that phase-altered signal gets combined with either the original signal, or another version with different phase alterations, this can cause huge dropouts in the lows where the two waves cancel each other out. So if you ever find yourself in a two-channel setup where the lows seem gutted out, flip the switch.
