Gibson 1975 bass catalog. Page 8. Details of the Les Paul Triumph (shown here in stunning white finish) and Les Paul Signature basses. White had only been listed as an option for the Triumph as of 1975, and cost an additional $30.
Both of these models are also included in the 1975 Les Paul catalog as well as this one, see page 5 for the Les Paul Signature and page 7 for the Les Paul Triumph.
In 1975 these two high end Gibson basses shipped in considerably lower numbers than many of Gibsons other models; to some extent this is expected, but the Les Paul Signature bass actually performed very badly this year, and was subject to a significant price drop by the end of 1975.
US zone 1 prices are as follows: Les Paul Triumph bass $679 (1/1/1975, 1/6/1975, 1/11/1975); Les Paul Signature bass $649 (1/1/1975, 1/6/1975) dropping to $499 (1/11/1975).
In the 1976 Gibson bass catalog these two basses were given a double page spread on pages 8-9.
