The musical instrument pickups, effects units and amplifiers designed and manufactured
by Harry DeArmond and Bud Rowe and later by Steve Tosh in Toledo, Ohio, from the 1940s to the 1980s, through Rowe Industries Inc.,
H. N. Rowe & Company, Rowe DeArmond Inc., DeArmond Inc. and Tosh Electronics, all of Toledo, Ohio, USA.
The Guild guitar company used a number of DeArmond guitar pickups.
The standard Model 2000, finished in chrome, usually with a white coil former, was used in the Starfire.
The X-175 in the 1970s was fitted at one time with a slight variation on the standard model 2000 pickup, in that its metal base flange was concealed under a 3-ply B/W/B plastic mounting ring and only two height-adjustment screws were used.
The Guild Artist Award guitar was marketed with an optional single pickup. For a period Guild offered a Model 1000 Rhythm Chief pickup. The pickup's insert was engraved 'Guild Artist Award by DeArmond'. Chrome-plated pickups had either a white insert with black lettering or black insert with gold lettering. This pickup was screwfixed to the side of the neck by means of the standard DeArmond short offset arm.
The Guild guitar Model M-65 Freshman was fitted with this standard-size pickup with a unique top detail, not found on any other guitar so far.
A Guild Capri CE 100D fitted with two adjustable centre-pole pickups, with two height-adjustment screws in a black plastic surround.
