Imagine that I set the pan pot to the centre indent and then I set the internal trim pots on my bass so that in this position there is a greater proportion of the bridge pickup than the neck pickup in the output.

Now if I'm playing and I pan the output so that it is fully clockwise towards the neck pickup position, will there be any bridge signal in the output or will this position of the pan pot always have neck only output regardless of the ratio's of the internal trim pots?

For some reason this came to mind in the traffic jam on the way to work this morning. My mind kind of works overtime when I'm bored.

I don't actually have any pan pots so probably shouldn't answer ... but that's never stopped me before. Ha!

I'd be willing to bet that panning fully in the bass pickup direction would be the same as having the pickup selector switch on bass pickup only.

What I'm curious to know is how that pan pot effects the output level of the individual pickups. For instance, if you have only the bridge pickup selected (via the switch) what happens as you turn the pan pot? Does the output level change between panned fully to bridge pickup and panned to "center"? Then does it fade as you pan all the way to bass pickup?

Hey, keep your eyes the road!

When your pan is fully rotated to the neck position there won't be any bridge pickup signal present. Gain trim settings will affect the way the pickups blend toward the middle of the panpot's rotation.
