Nope, that's actually the pickup pan switch! A first time for Warwicks, I believe.
How it works together with the pickup balance knob, I have no idea! I'll ask over at the Wick forums.
So to answer my own question, after receiving an answer from the Warwick forums:
The pickup SWITCH is the main pickup balance control. What the KNOB does is to determine the balance, or value of the SWITCH when it is in the center position.
Does that make sense?
Also, I'm trying to work out buying a P-Nut II model from the US in April. I have a friend who's going there, and I might ask him to bring it back home with him.
I asked Bass Central what they are selling it for, and when converting the price in $ they gave me, it was a tad more 1/2 (!!) the price in Sweden, thanks to the low dollar.
Maybe, just maybe I can make this happen.
Set out to get an upright yesterday, but the bass had already sold
...that deal was one time only, and the prices have all increased as of the new year. And the next shipment will be in July
Here's to me getting a P-Nut II!
