The Les Paul Signature was a semi-hollowbody guitar produced in the '70s. Like the Les Paul Recording, the Signature used low-impedance plastic covered pickups.  A bass version of this design was also produced in this era. Starting in 1974, the word "Gibson" was added to the pickup covers.  The Sunburst finish is significantly more rare than the Goldtop version of this guitar which does increase the value.
