A Gibson L6-S Custom
The Gibson L6-S was the working musician's descendant of the L5S jazz solid body electric guitar. It was the same shape - very much like a wide Gibson Les Paul, but with a 24 fret two-octave neck - the first Gibson guitar to have this.
The popularity of the L6-S gradually dropped after 1974, despite high profile endorsements from the likes of Al Di Meola and Carlos Santana. Pat Martino, John McLaughlin, Keith Richards, Paul Stanley and Mike Oldfield also used the model during this period. All models were dropped from price lists in 1979. The L6-S Custom remained in the catalog in 1980 and was still being made in the Nashville plant. The L6-S is now generally considered to be the most underrated of all the Gibson solid bodied guitars.
Late in 2011 The Gibson company has re-issued this guitar, with slight alterations:
The guitar is now called an L6S, not an L6-S, the bridge is a standard Gibson Tune-o-matic, less heavy than the Schaller-made rectangular bridges from the mid-1970s. The pick-ups are not the original's ceramic sealed Bill Lawrence-designed "super humbuckers", but two humbucking pickups with four-conductor split-coil wiring—a 490R in the neck and a hotter 498T in the bridge. This is similar to what is on offer in some current Les Pauls. Colours on sale in 2012 are "Antique natural" - like the original 1970s all-maple maple neck L6-S - and "Silverburst" with a baked maple fretboard. No ebony fretboard model is on sale. The current L6S neck does not feature the unique "narrow at the nut and wider near the body" taper of the 1970s guitar, but a conventional Gibson shape. The chambered body shape and 24 frets are of similar design to the 1970s classic.
L6-S Custom 1973–80
Over 12,000 L6-S Custom instruments were made. Maple body, and set neck with a choice of maple or ebony fingerboard. Controls include a six position pickup selector, master volume, mid-range and treble roll-off controls. At the time of its introduction, the L6-S Custom was simply called the L6-S, not gaining the "Custom" badge until later, when the simpler L6-S Deluxe was introduced. The L6-S and L6-S Custom are identical.
The L6-S Custom is noted for its six way rotary selector switch, complete with "chicken head" pointer knob. Starting with switch position #1, in the most counter-clockwise position, the available pickup switching options are as follows:
- Both pickups, in series
- Neck pickup, alone
- Both pickups, in parallel
- Both pickups, parallel out of phase, with the neck pickup's bass response restricted thought a series capacitor.
- Bridge pickup, alone
- Both pickups, series out of phase.
The capacitor in the #4 position gives a fuller tone than the otherwise very nasal out of phase tone. The capacitor serves to limit the low end response of the neck pickup, and also phase delays the signal from that pickup, resulting in a fuller tone, not too unlike the #2 and #4 switch positions on a Fender Stratocaster guitar.
Note that these switching options are for the original 1970s L6-S with sealed ceramic Bill Lawrence Humbuckers and are somewhat different for the 2011- reissue L6S, which use 490R/498T split coil pickup switching and different wiring.
L6-S Midnight Special 1974–79
Some 2,000 L6-S Midnight Special instruments were produced, with maple body, and bolt-on maple neck with a maple fingerboard. Controls include a pickup selector, master volume, and tone control; it is strung through the body.
L6-S Deluxe 1974–79
Around 3,500 L6-S Deluxe guitars were produced. The Deluxe had a set maple neck, with a rosewood fingerboard. Controls include a pickup selector, master volume, and tone control. Strung through the body.
L6S reissue 2011-now
Now called the L6S rather than L6-S, this is basically a re-issue of the classic L6-S Custom model, not the Deluxe version. Set maple neck and maple body, 490T/498R Alnico split-coil humbuckers are now used, six- position switch, a standard Tune-o-matic bridge and stop tailpiece. The neck uses Gibson constructon: a maple fingerboard over the trussrod and maple neck, rather than an insert in the back of the neck like Fender maple fingerboard/necks. The 6-position switch in the original L6-S previously provided all possible connections of two pickups; now, instead, according to the Gibson literature the series in-phase, series out of phase, and parallel out of phase positions have been deleted in favor of 3 new split-coil positions utilizing just one of the 2 coils in a humbucker, resulting in these selections: bridge humbucker, bridge single coil, both single, both humbucking, neck single and neck humbucking. This provides more pleasant selections, but eliminates the previous more radical special-purpose settings of the original Bill Lawrence design. As of 2013 Gibson refuses to release the new schematic. Each L6S is now setup on the Plek machine, resulting in consistently good action direct from the factory.
