Hi guys! I installed this EMG PJHZ set for a friend. Easy and simple installation with quick connect cables. I don´t need any reading glasses yet, but I managed to mess it up a bit. So what have I done wrong here? The bass has a very low output volume. A LOT lower than it should have. It gets ever lower when I turn full volume on the bridge/jazz pickup. The tone knob seems to have almost no function, at this low volume level at least.
