I believe Dimarzio's first replacement pickup for the P90 was called a DLX-1 (available only in creme)and were advertised as a "twin humbucker replacement for the Les Paul Deluxe"... they were comparable to a super distortion....Now they make several P90 sized replacements (the DLX-1 had the same specs as a DP154)... The Les Paul Pro models were ebony & had creme P90's vs Deluxe's chrome mini-humbuckers.
