This example came up for auction in January 2009 with an asking price of $1,800, but didn't sell. Given the turmoil in the financial markets at that time it's not surprising. Anyway, interesting guitar based on the description, although I haven't been able to dig up any information on Earl Brooks.
"RUMOR HAS IT THAT THIS GUITAR BELONGED TO A SESSION GUY NAMED EARL BROOKS THE STORY GOES THAT DURING THE EARLY SEVENTIES THIS GUITAR WAS USED BY NONE OTHER THAN KEITH FOR SOME RECORDING SESSIONS! AN ANTIQUES DEALER FRIEND OF MINE WAS TRAVELING THRU MEMPHIS AND NASHVILLE BUYING FURNITURE IN THE MID NINETIES WHEN HE CAME UPON THIS GUITAR HE KNEW I LOVED OLD GUITARS AND HE PICKED IT UP FOR ME. THE GUITAR HAS A GREAT WELL WORN FEEL LIKE A GREAT SET OF COWBOW BOOTS THE NECK HAS SEEN SOME SERIOUS PLAYING IT FEELS SO COMFORTABLE, THE PICKGUARD HAS THE TYPICAL CHIPPING AROUND THE INPUT JACK THUS THE WASHER ( WAS THERE WHEN I GOT IT) THE PICKUP HAS THE USUAL CRACKS WHERE THE PLASTIC MEETS THE METAL. OTHERWISE THE GUITAR SEEMS TOTALLY ORIGINAL. THERE ARE SOME MINOR SCRAPES BUT NOTHING THAT COULDN'T BE POLISHED OUT..THE PICKUP IS A ROCK TREBLE COMES WITH THE ORIGINAL CASE WHICH IS IN FAIR SHAPE MISSING ONE LATCH BUT STILL DOES ITS JOB . I PERSONALLY LIKE THE ENGRAVING AND PATINA THAT THIS 35+YEAR OLD GUITAR HAS, IT WILL SHIP IN ITS ORIGINAL CASE..."
