Les Paul & the Log guitar

c1948…Les Paul playing “The Log” and tinkering with multi-track recording in his apartment, with Mary Ford in background.

Paul was dissatisfied with acoustic-electric guitars and began experimenting at his apartment in Queens, NY with a few designs of his own. Famously, he created several versions of "The Log", which was nothing more than a length of common 4x4 lumber with a bridge, guitar neck and pickup attached. For the sake of appearance, he attached the body of an Epiphone hollow-body guitar, sawn lengthwise with The Log in the middle.

This solved his two main problems: feedback, as the acoustic body no longer resonated with the amplified sound, and sustain, as the energy of the strings was not dissipated in generating sound through the guitar body. These instruments were constantly being improved and modified over the years, and Paul continued to use them in his recordings long after the development of his eponymous Gibson model.

In 1945, Richard D. Bourgerie made an electric guitar pickup and amplifier for professional guitar player George Barnes. Bourgerie worked through World War II at Howard Radio Company making electronic equipment for the American military. Barnes showed the result to Les Paul, who then arranged for Bourgerie to have one made for him.

While experimenting in his apartment in 1940, Paul nearly succumbed to electrocution. During two years of recuperation, he relocated to Hollywood, supporting himself by producing radio music and forming a new trio. He was drafted into the US Army shortly after the beginning of World War II, where he served in the Armed Forces Network, backing such artists as Bing Crosby, the Andrews Sisters, and performing in his own right.

Paul had never been happy with the way his records sounded. During a post-recording session talk with Bing Crosby, the crooner suggested Paul try building his own recording studio so he might be able to get the sound he wanted. At first Paul discounted the idea only to give it a few more minutes thought before deciding Crosby was right.

Paul started his own studio in the garage of his home on Hollywood's North Curson Street. The studio drew many other famous vocalists and musicians who wanted the benefit of Paul's expertise. The home and studio are still standing, but both had been moved to Pasadena at some point after Paul no longer owned the home.

In 1948, Les Paul was given one of the first Ampex Model 200A reel-to-reel audio tape recording decks by Crosby and went on to use Ampex's eight track "Sel-Sync" machines for Multitrack recording. Capitol Records released a recording that had begun as an experiment in Paul's garage, entitled "Lover (When You're Near Me)", which featured Paul playing eight different parts on electric guitar, some of them recorded at half-speed, hence "double-fast" when played back at normal speed for the master. ("Brazil", similarly recorded, was the B-side.)

This was the first time that Les Paul used multitracking in a recording (Paul had been shopping his multitracking technique, unsuccessfully, since the '30s. Much to his dismay, Sidney Bechet used it in 1941 to play half a dozen instruments on "Sheik of Araby"). These recordings were made not with magnetic tape, but with acetate discs. Paul would record a track onto a disk, then record himself playing another part with the first. He built the multitrack recording with overlaid tracks, rather than parallel ones as he did later. By the time he had a result he was satisfied with, he had discarded some five hundred recording disks.
