Thanks everyone. I didn't think it would make any difference, but I guess I just wanted some outside opinions.
Actually I did also change the bridge. Ended up putting a BasAssII on as I was told it was a drop in replacement. I think one of the holes was about .5mm out. With regards to the bridge, will I have to adjust the bridge, esp with regards to the saddle positions, length wise? When I compare their positions to those of the standard bridge they are quite different. Height wise the action is a little lower and I'm getting some buzz, but that's easilly fixed.
The only other issue now is that I've just discovered that one of the push/pull pots I've used is broken, when in one position only the top coil of the neck pickup works. Just as well I have a spare. For those interested I used the DiMarzio PushPull Volume Control Dual Sound wiring option.
Regards
Craig
