This guitar came up on a Craigs List ad in July 2013 with an asking price of $800. It's been heavily modded of course, with the biggest alteration being a second pickup installed just after the neck. This probably involved some routing out of the neck joint where it bolts to the body, so you have to wonder whether it's still stable or not. Here's what the seller had to say:
"I have a 1970 Ampeg Dan Armstrong Lucite 6 string guitar for sale. The serial number A1426D shows that it is an original from the 70's. I talked to Ampeg and they said that it was not one of the remakes that came out around 2000-2002. If it was the serial number would have more digits, so yes this is a vintage guitar."
"This guitar is not 100% original though. Someone made modifications to it before I obtained it. It has a metal plate at the head of the guitar, different hardware, pickups, and pick guard than what would have been on it from the manufacturer. I am selling it because i need money for other hobbies and it is too cool of a guitar to sit in my closet. IT NEEDS TO BE PLAYED!!"
"The guitar does have some damage. The corner of the pickguard is broken and has a crack but can easily be replaced. The metal plate at the head of the guitar has slightly separated from the wood and the wood there has a small chip in it. The input jack needs to be re-soldered, but I'm going to get that repaired in the next couple days."
"I'm selling the guitar with a strap and case. If you are interested, i have some guitar cables and a distortion pedal as well for $50. So if you are looking for the complete package to learn to play guitar this is it!!"
February 2016 - A1426D comes up for auction again and finally sells for $800 on May 31. Here's the description from the seller...
"I am selling my Ampeg plexi guitar. I bought it from a collector 10 years ago and it has mostly been sitting in the case since then. It is an original 1970 guitar but has some modifications that were done to it before I obtained it, so I can't offer much info on that."
"It does play but the input jack connection isn't very good and needs to be replaced. The pick guard is broken so you could put a wood one on like the original or color of your preference. One of the switches doesn't seem to change tone so it might not be hooked up. There are some dings and scratches on it but all minor..."
"This would be a great guitar to bring back to a like new original state or make it your own and not feel guilty since it has already been altered. Guitar strap and hard case included. This guitar does play but needs a little maintenance to be great again so I am selling this used as is. If you are unsatisfied I can try to work with you."
February 2017 - back again on Craigslist (Noe Valley, CA) this time with an asking price of $1,800. Seller said: "Great example of the first "super" guitar and either Dan Armstrong or someone with super skills dropped in a DeArmond neck pup, a Kahler floating Trem, and a shiny silver plate to cover up the ugly faux wood-grain Formica in the headstock. I invested roughly $800 getting this guitar to its maximum potential (including Plek'd) and it's damn close! 99% of these guitars list at $4000 and above. Take it to the next level with this super guitar which I think is way cooler than stock at half the price!"
