This guitar came up on Ebay in June 2015 with a buy-it-now price of $3,700. That seems reasonable for today's market, given that the guitar comes with the valuable ST pickup. The original pickups would have been the RT/CB pair and it's a shame they haven't survived given the above-average condition of the guitar. Very interesting bridge too - not certain if this is a factory special or an aftermarket piece. Nut has been changed out to brass stock, likely at same time as the bridge work. Note the cool slot-style tuners - these are rare! Case is not OEM, but seems like it has an Ess & Ess sticker on the inside...another mystery. Priced to move!
"Up for a buy it now or best offer is a super cool 1969 or 1970 Ampeg Dan Armstrong plexi guitar S/N A 1320 D. This one is equipped with the holy grail of D-A pickups, the one Ron Wood, Joe Perry, and other greats raved about and the only one they used in this guitar, the Sustained Treble Humbucker. It is an AMAZING sounding pickup, fat, smooth, with wonderful bite, its just an awesome pickup."
"This guitar is in amazing condition. There are no scratches to speak of on the plexi body. The neck's frets are in as new condition, as is the Brazilian rosewood fingerboard. This guitar was not played very much at all in the last 45 years!!! What keeps this guitar from being near mint, and it might be just the wood grain in the neck, but on the treble side where the maple meets the rosewood board, the maple is discolored or darker than the rest of the neck (see pics). This guitar is also equipped with the more rare intonated nickle plated bridge (looks like the very top part of a LP Jr bridge but is original as it has the locater pin on the bottom, to center it in the chrome bridge base. This is a just cool guitar, any way you look at it, and it is one of the best slide guitars ever with this pickup!!!!"
"The guitar comes shipped in its original hard case. The case got water damaged to the body end a LONG time ago, while thankfully the guitar was not being stored in it. It suffered interior damage and damage to the bottom, but this could definitely and would be worth while restoring (re line it and fix the damaged plywood while the lining was removed). The Tolex is actually pretty good everywhere. Shipping will always be combined when possible! Shipping will be fairly expensive due to the value with full insurance. International bidders MUST contact me first prior to bidding, or I will cancel or not entertain any offers. Please call if you want to discuss this in person, thanks, Rob 315 298 6797.

A1320D next came on the market in November 2015 through internet dealer The Music Zoo with an asking price of $3,299.
"The radical acrylic body and killer humbucker sound made the original Dan Armstrong Lucite guitars some of the most sought-after instruments in rock history, and this vintage 1969 example shows us why! The Lucite body is bolted to a comfortable Maple neck that's topped with a stunning piece of Brazilian Rosewood. The Formica pickguard is topped with a faux-Rosewood veneer and combines with the brown plastic humbucker for a unified look. The three-position toggle switch provides some atypical sounds, from an in-your-face all-controls-bypassed tone, to a "cocked-wah" tone that's perfect for rhythm. The middle position engages the master Volume and Tone controls for access to all of the other sounds you desire!"
"This instrument is in overall very good vintage condition, with player's wear as would be expected in an instrument of this age. The bridge was replaced with a direct-fit pre-intonated model, and the nut was replaced with a brass model for more high-end presence. The original hardshell case is included here, however the interior is in fair condition with some damage to the liner as shown in the photographs."
