The Guitar of the Month Showcase series of brochures was issued by Gibson in 1972. Each discussed the 'outstanding features' of a high-end gibson model. The Gibson Super 400 CES brochure is reproduced here. Part 1 (below) shows the guitar and it's features. The reverse side of this sheet had the outer covers and text describing the development and musical purpose of this superb Gibson guitar.
ADVANCED AUDITORIUM BODY SIZE The Super-400CES with its 18" wide body creates a powerful, resonant tonality that is unequaled. Referred to as the "tone chamber", this cubic air space in relation with the vibrant qualities of the carved top, creates the "heart and soul" of the ultimate tone reproduction.
CARVED AND HAND GRADUATED SPRUCE TOP An adaptation of fine violin construction, the carved and hand graduated Spruce top is the foundation of pure acoustical reproduction. The Spruce used is of the finest available in the entire world. A large Spruce block is actually carved to form the ultimate shape and exact dimensions required to offer excellent tonal response. The Spruce used on the S-400CES is from a tree 45O to 500 years old. Only a very small portion of the world's Spruce yield is good enough to use in the production of S-400 instruments. This material must be straight and close grained in order to offer superb appearance and performance.
CARVED MAPLE BACK The carved Maple back assures excellent tonal performance. The material used on the back of an instrument is critically important to the projection of tone. Carved and graduated to demanding specifications, the Maple back offers a brilliant and responsive "presence" in tonality.
SCALE LENGTH The S-400CES incorporates a 25 1/2" scale length. Longer than most conventional electric guitars, the S-400CES scale length is designed in direct proportion with the body size and tailpiece length. The scale length is very important to the proper "feel" and tension of the guitar strings.
"F" SOUND HOLE DESIGN This Gibson innovation contributes a great deal in the performance of an acoustic, electric guitar. Even more so when incorporated with a quality, carved Spruce top, the placement and size of the "F" sound holes are ultimately important to a balanced sound.
ADJUSTABLE TUNE-O-MATIC BRIDGE This innovative feature serves a dual purpose. First, it allows flexibility of "tuning" a combination of string gauges. Secondly, it enables adjustment of the action height relative to the fingerboard.
GIBSON ADJUSTABLE TRUSS ROD First developed by Gibson, the adjustable truss rod has often been copied but never duplicated. This feature assures perfect alignment of the guitar neck at all times.
LAMINATED MAPLE NECK The neck of the S-400CES is laminated to offer increased strength and aid in the prevention of neck warpage. The grain of the outside pieces of Maple run in the same direction while the center piece is reversed.
MAPLE RIMS Gibson employs the use of a traditional craft of hand bending the Maple rims on S-400 instruments. Accomplished with a heated form and roller, this operation assures a perfectly contoured rim that retains its shape and rigidity.
GIBSON HUMBUCKING PICKUPS Gibson Humbucking pickups have become known to millions of guitarists as the finest on the market. Although the design and name have been copied, the internal function cannot be duplicated due to a protective patent. The purpose of the Gibson Humbucking pickup is to offer a consistent, strong output signal void of extraneous noise. The clear bell like guitar tone is a result of special shielding and unique pickup coil design. Although sensitive to the smallest string vibration, this high impedance pickup will reject interference such as hum, static or radiated noise.
