In some ways, the Gibson ES-150 DC can be considered a full-bodied version of the thinline ES-335TD. Both were made from the same materials, and shared much of the same hardware and ornamentation. They were the same scale, with the same number of frets. The most obvious difference was in the dimensions: the ES-150DC was 1 1/4" deeper at 3", compared to 1 3/4" of the ES-335TD. But the ES-150DC was completely hollow - it lacked the central maple block of the 335. There were differences in the circuitry too (see below).
The ES-150DC was included in price lists from September 1969, with an initial launch price of $495 ($40 more than the 335), until January 1975. It was available in Walnut, Cherry and Natural finishes, though Cherry was dropped after 1970. Although it was only listed until 1975, and over 99% of the production total were shipped before '75, a handful of Cherry-finished ES-150DC guitars left the Gibson Kalamazoo plant between 1976 and 1979. In total 2801 instruments were produced, in Walnut, Natural and Cherry finishes, in a ratio 70%:25%:5% respectively.

The ES-150DC circuitry was a step away from the usual two volume / two tone layout of the ES-335, though the two models did share the same Gibson humbuckers, parts 13506 (bridge) and 13508 (neck), with the usual three-way selector switch. Whilst it had a volume control for each pickup, and an additional master volume on the lower front of the guitar, it did not have the usual tone controls. Instead it had a single master bass and master treble control, similar to the new low impedance Les Paul models developed at the same time.
