I AM A STUPID FOOL ! ! ! - Duane Eddy 400 that I sold - jackass me !!!
I'm like that too. A really cool '93 archback, standard scale, 1 11/16" nut "prototype" F20 that was a closet queen. It's living with a fellow LTGer SouthernGuild in Oz. I'd love to have another just like it, but will never find one in this condition again.
"FF" serial numbers were only used on prototypes, in this case for the reintroduction of the F20 to the product line.
It had a really unique punchy sound, but at the time I thought that bigger was better (and still do mostly). I've had saved searches on eBay that have turned up nothing for years. I guess they didn't make many like this!
