Kitty Hawk has been around for nearly 50 years according to the time frame established by this ad. Their website notes:
The name KITTY HAWK has long been extremely powerful, articulate sound tube. No frills or gimmicks, but with consistent practical orientation in sound and handling.
“No frills” certainly applies to this ad, taken from Guitar for the Practicing Musician, August 1988. Though the company still appears to be in business, there’s not much information about U.S. distribution.
