The LP series lineup was LP-1000, LPC-800, LP-600, LP-500, LP-400.  LPC-800 was the only Les Paul Custom model.

Popularity of guitar models depend on popular guitarists of the age.  The 70s was the age of Les Paul and Stratocaster.  In the 80s, it was the age of decline for Les Paul guitar.  Stratocaster survived by gadgets of replacement pickups and locking tremolo unit.

The LP series was started around 1985, but then Les Pauls seems to
have been ended as guitar of well sales.  YAMAHA might adapted plied body because they gave up well sales then.  I suppose that the pancake body was not the cause of commercial failure, but YAMAHA might have already given up success of the series itself from the beginning.

YAMAHA provided 2 type of pickups for LP series.  LP-1000 and LPC-800 equipped newly developed SPINEX pickups, and ALNICO V pickups for LP-600/500/400.  ALNICO V has high output but easy to make howling, powerful and wild.  SPINEX has lower output, gentle and like a model student.  4.11kg(includes strings).
