I really, really like blackonblack. Nice. Soapbox? Are they just another shape of P90s?
There are two descriptions of P-90 pickups - Soapbar and Dogear. The descriptions have to do with the type of covers and mounting of the pickups, but internally they are the same thing.
If you look at Dave Sloven's post above (post #79), he has a soapbar P-90 pickup on his SG Junior. They are called that because their shape sort of resembles a bar of soap.
Kevinpaul's pickups in post #78 above show the Dogear P-90 pickups. They have triangular flanges (the "dog ears") on each end of the pickup. These are used to fasten the pickup to the guitar body.
