This early Dan Armstrong came up for auction in August 2015 and sold for $1,538. Although the pick guard has been changed out to a reissue series version, the owner did not drill any extra holes, so it could be restored at some point. The original guard is included in the sale, but has a large hole where the jack used to mount. Comes with a vintage Gibson case.
“I've owned this guitar since 1971, and considering it's age it is in good condition. The back of the neck shows signs of wear- small abrasions in the finish, due to years of use. In 2007, a new pickguard and 3-way switch were installed. The specs of the replacement pickguard, (originally in 1970 a thin veneer) modernized with an aluminum backing, are not exactly the same as the original. Only two of the eight philips head screws line up, and my repairman improvised a method of attaching the new pickguard to the body using "mounting tape," adhesive on both sides. I recently removed and replaced the 6 1" to 1.5" tape points, as after eight years, the adhesive quality of this original repair lost its strength. The pickguard is securely attached to the body, however, if in the future work is needed internally, this tape would probably require replacement. The other 6 mounting screws will be included...my repairman simply did not want to drill into the lucite to avoid damage to the body."
"This is a 1970-71 Ampeg Dan Armstrong clear lucite electric guitar. Please read the "Seller's Notes," as I want any potential buyers to be very aware of the "pickguard predicament" which I have explained. This rare guitar features a bolt on maple neck with a 24 fret rosewood fingerboard, Schaller tuning machine heads, and the original wooden bridge. The guitar comes with two of the unique "slide in" pickups, marked "CB" and "RT." It features a 3 way switch, two potentiometers, one controlling volume and the other controlling the tone. The case is a Gibson case, which was supplied by the original seller. The two end latches are intact, but the middle one is missing the top half..."the keeper," although it does have a new handle. This is a very unique and interesting guitar, with a great sound quality. Please examine the photos and contact me with any questions you may have...and thanks for your interest in this personal heirloom!"
"Listing revision 8/18/15: I have learned that this guitar is one made in 1969. I have also added a photo of the serial number. Also, the potentiometers are original 1969 issue, therefore there is some scratchy noise evident during adjustment."
"Listing Revision 8/18/15: The two pickups with the guitar are a "CB" and an "ST". There is no "RT". Also, a small point, but I only have 6 pick guard screws TOTAL. 2 are in use, and 4 will be sent with the guitar."
August 2017 - A237D is listed on Reverb through dealer Echopark Guitars of Detroit, MI, with an asking price of $2,300.
