Gibson 1970 Les Paul catalogue. Page 6. The only catalogue appearance of the Gibson Les Paul Professional. This low impedance guitar was quickly replaced by the Les Paul Recording guitar in 1971. Like the more expensive Les Paul Personal it had been designed for studio and live use, but lacked the built in vocal microphone jack.
Though a functionally equivalent guitar, it was also not so highly appointed: nickel, as opposed to gold hardware, no headstock inlays (beyond the Gibson logo) and a rosewood rather than ebony fretboard.
The Les Paul Professional has many of the exciting features found on the LP Personal; low-impedance pickups; fast, low action neck; and a 24 3/4" scale. But perhaps the feature you'll enjoy most is the modest price tag that accompanies this "professional" guitar.
The Professional was designed to work with special low impedance amplifiers such as the Les Paul LP-12 on page 9. To operate at normal signal level on a standard guitar amp, a special low impedance transformer had to be used. See a description of this on page 11.
