And have received the Warman p pickup and fitted it, it was between that, a Dimarzio model p and a Dimarzio split p but I chose the Warman over the Dimarzio because the Dimarzio p pickups are known to be a little shy in the treble frequencies.
Anyway, fitted it and I like it a lot so far, this is not a dull,thumpy SPB1 type of pickup(I detest the SPB1 btw) this seems to have a very full range sound, almost like a single coil in a split p format (still not quite as bright as a single coil but the highs don't rapidly drop off like most p pickups), works well with the Ultra jazz in the bridge position too.
