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.
Storm Series of archtop guitars and basses (Thunderhead, Hurricane and
Tornado guitars and Typhoon/Williwaw bass) were fitted with seven
different DeArmond pickups. The pickups' plastic mounting rings are the
same size across the range.
The three photos above show two different examples of Ovation's Thunderhead guitar. This model is fitted with two pickups which employ the same type of offset height-adjustment screws as used in the DeArmond Model 2000 pickup.
The height-adjustment screws are located in the same position in both
pickups, but the pole-pieces' centres are different for the neck and bridge
pickups. This spacing difference is most apparent in the right-hand photo. The
pickups are installed so that the poles are facing outwards and as these
pickups are fixed to the bezel with with three screws, each pickup can be easily
identified (Left-hand and centre photos copyright Guitar Tree, Phoenix, Arizona. Right-hand photo copyright Dan Wyatt).
This 'six-pole and blade' pickup was used in the Tornado Eclipse. Only one version of this pickup was installed in both
Bridge and Neck positions. Hofner used a guitar pickup very similar in outward appearance to this one in some of their guitars. See the section 'Non-DeAmond products' for more details.
This 'twelve-pole and two-slot' pickup was used in the Model Hurricane 12-string guitar. The outer pole-pieces are centred on the edges of the two slots, making this the bridge version
The outer pole-pieces are closer together than on the above pickup, which would suggest that this pickup should be fitted at the neck, and not at the bridge where shown.
The two pickups shown here - neck and bridge - mistakenly have the same pole-piece spacing, in the Model Hurricane 12-string guitar. The slight difference in the pole-piece spacings between both pickups is makes this an easy mistake to make.
Although not in the 'Electric Storm' range, the pickup shown is fitted in the Ovation Jerry Reid model guitar. It appears to be a DeArmond housing without visible pole-pieces.
The Typhoon bass used two pickups, each with eight poles and two slots.
