This rare fretless bass is one of the "black" series where Ampeg featured a black pickguard, headstock, truss rod cover, and thumb rest. Completing the look is a fretboard that appears to be made out of ebony. It's a great looking bass and this example seems to be in superb condition, with the only change being a replacement bridge saddle. Came up for auction in August 2015 for $2,295, which includes the OHSC.
