This Dan Armstrong came up for auction in February 2009 and sold for $1,484. I believe the pickup selection is CB and JT. OEM case is there, but you have to wonder is it literally being held together with duct tape. Anyway, here's what the seller had to say...
"A true rock and roll relic. It weighs 9 lbs 9 oz. It measures 1 ¾ inches wide at the nut, quite wide for an electric, and the neck is extremely smooth, chunky, beautifully grained maple. You would think such a wide and thick neck would hinder your playing, yet it is incredibly comfortable and fast. I like that it has 24 frets and easy access to even the highest. The fingerboard is wide and only slightly radiused, making it quite flat and allowing for extremely low action. The action is so nice it appears to have been given the “Plek” treatment. I can only imagine how nice it would be if it were actually Plekked! The frets are beefy enough to allow very easy bending, and have little wear showing in the first position, almost none in the others. This guitar is a true relic from the past, and it has been played a lot through the years by its various owners. Although the instrument is in perfect playing order, and is a terrific player, it has some accumulated some "battle scars." There is a chip on the upper bout that is shown in the one of the photos. There is also a small rough area shown in the photo with my finger pointing to it, and a crack where the strap button screws into the horn of the body, which is also shown in one of the photos. Other than that, the guitar is in excellent shape. The guitar is completely original, as far as I know, except for the strap locks which came with the instrument when I bought it. There is an extra pickup for it."
"Two things- first, I want to clarify that this is an “original” in the true sense; it was built in the late 1960’s by Ampeg, it is not merely a reissue of the original design. Secondly, I forgot to mention that about 25 years ago, the back of the maple neck had been professionally sanded and oil treated, so it has no varnish on it, but varnish remains on the back of the headstock and at the base of the neck where it joins the body. The reason for this treatment was to create a slick, smooth neck, like an old Charvel, which does not stick to your hands when you play. It is a big improvement from the varnish for playability. The neck is in excellent condition and completely smooth."
