A950D
Here's a very nice early 1970 Dan Armstrong guitar, serial number A950D. This guitar was being offered by Japanese internet dealer Guitar Tribe for ¥348,000, which is approximately US$3,500 (guitar is sold). The description of the guitar was entirely in Japanese so I wasn't able to see if the guitar came with its original hard shell case, but certainly the photos of the guitar itself show a very nice and intact example of a Dan Armstrong. Comes with a single RB pickup, which is perhaps our favorite of the single-coil options.
