2 and 3 are my favourite. From memory I think it goes it the order:
1.Pickup blend set in the middle using the both jazz pickups
2.Pickup blend is biased towards the bridge pickups about 75%, still using both jazz pickups
3.Pickup blend all the way to the neck pickup
4.Pickup blend all the way to the bridge using both jazz pickups
5.Pickup blend all the way to the bridge using one jazz pickup(the one closest to the bridge)
Remember this is what I think I had it as when I was recording. You can tell what is pretty much from the tonal characteristics from each clip.
number 4 is a great one but im not a huge fan of jazz bass pickups. Im a P man all the way and is the ONLY reason for the sale.
I would love me a Warwick Stryker as it has a double P bass pickup. Same with the Warwick Buzzard, so if you have any of them, please give me a buzz
Also would be interested in a Sadowsky P bass with a bridge Pickup or anything that is neck Pickup orientated.
