I HAVE AN EBONY BLACK SUPER AXE THAT I BOUGHT NEW, WITH THE HARD CASE AND A MATCHING AMPLIFIER BY GRETCH AND I WONDERED IF SOMEONE COULD TELL ME HOW TO FIND THE VALUE OF IT.THE GUITAR IS A MODEL # 7681 SERIAL # 3-8045. THE AMP IS A BROADKASTER MAXILEAD – 60 WITH TWO CHANNELS AND FOUR HOOK-UPS WITH REVERB AND TREMOLO ON ONE CHANNEL. GUITAR HAS BUILTIN REVERB, TREMOLO AND SUSTAIN WITH CONTROLS RIGHT AT YOUR FINGER TIPS. BOTH GUITAR AND AMP ARE IN PERFECT CONDITION AND EVERYTHING WORKS. IT HAS ONLY BEEN PLAYED A LITTLE BIT AS I AM A NOVICE PLAYER. I THINK I BOUGHT IT IN THE 70s OR EARLY 80s.
