So an idea popped into my head a few nights ago and I've been thinking about it ever since. What if on a double split coil bass you used just the E/A coil on the neck pickup, and just the D/G coil on the bridge pickup and combined them in series. So you had more bass on the 2 low strings and more treble on the two high strings. This might not work well for scales but I think it could be cool for things like octaves, an example (a terrible one but it's the first one that came to mind) is when playing seven nation army by the white stripes I usually switch to the bridge pickup to play the octave parts and then switch back to the neck, this way I would just automatically have the octave parts on the bridge and the bass parts on the neck. Has anybody ever done anything like this before and if you have what did you think about it?
