The Fred Gretsch Mfg. Co. was the first high-profile manufacturer to fit DeArmond pickups to their instruments when in 1949 they fitted the Model 2000 pickup in all of their electric models. They used gold-plated and chrome-plated versions with black coil formers. Gretsch also used a four-string version of the Model 2000 pickup in chrome with a black coil former for some Tenor guitars. See example below.
Gretsch literature referred to them as Dynasonic Fidela-Tone pickups. This name was never used by DeArmond. Gretsch’s successful association with DeArmond ended only after DeArmond signed an agreement with The Chicago Musical Instrument Company (CMI), manufacturers of Harmony and many other brands, to supply them with pickups. When the Model 2000 pickup was first introduced, it was available in one height only. This meant that these pickups sometimes required a spacer when fitted at the bridge.
In their July 1965, 8-page purple catalog (Form 215), Rowe Industries introduced a bridge version – Model 2000 T – with a metal frame height of 9/16″ ( 14.3 mm.) from flange to top of pickup. The original pickup was then renamed the Model 2000 B, for installation at the neck.
Rowe Industries, the name of Bud Rowe’s company at that time, was embossed into the underside of the coil former in these pickups.
