The eagle and not so eagle-eyed will also spot a different pickup has crept into the fray? I decided to replace the bridge with a Squier one as could not find a Fender and it is the old twin saddle type. Whilst the bridge is no wider than the non OEM one fitted, the saddle spacing is slightly wider and my E string was way adrift from the pole screw on the bridge pickup. So I decided to experiment with pickups, first the P Bass ones(cheapies), then the Squier Jazz one. The body had been routed for a Jazz at some time beneath the control plate. I just fabricated the plates myself and in fact rather than drill any more holes in the body (its like Blackburn under there), the Jazz plate is held in place by the Bridge cover, again a Fender part. Many will know, depending on which was around you have the bridge cover can influence the sound if the damping rubber is still in place. My bridge cover is naked underneath. One thing I have noticed, is that without changing anything but the bridge pickup, how the different pickups react with the neck pickup. Each one is very different and also where they interact when blended too. The two Humbuckers as bought were a bit OTT tonewise and a bit full-on.
