Very nice example of a 1970 DA bass with all original parts. Only issues are a washer over the input jack (what lies beneath?) and a non-OEM case. Bidding started at $200 and the bass ultimately sold for $1,425.

Back on the market in May 2016 with an asking price of $2,350. Electronics and pickguard have been changed out, as further described below.
"Circa 1969 Ampeg Dan Armstrong ARMB-1 “see-thru” Lucite (acrylic) bass. S/N 1140A; original CTS 200k potentiometers dated 20th week of 1969."
"Good condition…see photos for aesthetics; a few small scuffs, scratches, and wear marks from normal use, but there are no major defects or significant flaws; no functional issues - professionally setup by local well-regarded luthier; original pickguard typical failure around the jack…typical repair previously applied using two large washers."
"Current modifications: The original pickguard replaced with 1/8*-thick clear plastic guard."
"The original wiring harness, which consisted of CTS 200k potentiometers and two parallel 0.47 mF 400 VDC paper tone capacitors were replaced; instead, a vintage-spec wiring harness was installed, but with CTS 250k (actual reading) potentiometers and a single Sprague Vitamin-Q 0.1 uF 400 VDC tone capacitor; this change makes this great bass even better, giving it a little more presence and results in a tone range that is more useful; professionally installed by local well-regarded luthier."
"Original volume and tone control knobs replaced with DeArmond ice-cube-style knobs; going clear and raw all the way! All original parts were retained and are included."
