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.

Non-DeArmond products

 Some pickups produced by other manufacturers are sometimes mistakenly assumed to have been manufactured by the Rowe Industries Inc./H. N. Rowe & Company/Rowe DeArmond Inc./DeArmond Inc./Tosh Electronics group of companies, all of Toledo, Ohio, USA.

A selection of the most common examples is shown below.  Identifying these pickups in this manner does not infer criticism on them in any way, but merely clarifies their source.

This site would gratefully appreciate any information on this particular subject.

  These pickups, shown here with a black top, but also available with either a chrome or white top, installed in some Guild guitars including the X-50 archtop, were not manufactured by DeArmond.  It is likely that they were manufactured by the same company that manufactured Guild's chrome humbuckers, because the above pickup's connections terminate in a very small insulated connector unit exposed on the underside of the pickup - the same arrangement as on Guild's humbucker.

This single-coil pickup with non-adjustable individual pole-pieces is fitted in some Guild Guitars, and is sometimes referred to as the 'Mickey Mouse' pickup.

This pickup was fitted to a number of Kay guitars.  The cover and bezel were manufactured as one pressing.  The pickup is quite shallow, enabling it to be surface-mounted on a pickguard or recessed with the bezel hidden.  The date of manufacture was sometimes stamped in ink on the underside of the pickup.  Note the closeness of the two fixing holes to the pickup body proper.  Several cosmetic variations to the plain chrome top exist, including an embossed diamond pattern and a printed black and white pattern.

This pickup fitted to a Kay mandolin was manufactured by Kay.

           This pickup is found on a number of Japanese guitars, and may have been manufactured by Teisco.  The combination of slots and pole openings filled in a gold finish could contribute to its mistaken identity as a DeArmond item.

Another Japanese pickup

  This pickup fitted to a Harmony H53 guitar was manufactured by Gibson.

  This pickup, fitted to a Harmony H59 guitar is a model P-13, manufactured by Gibson.

     Magnetone, guitar dated 1965 with pickups similar in appearance to those manufactured by DeArmond and fitted in the Wanderer guitar and others.  The pole-pieces in the DeArmond pickup are individual pin-magnets, whereas these pole-pieces shown are dome-headed rivets with rough-cut magnets underneath as seen in the second photo.

  While the pole-pieces and the coil former design are very similar to the recessed version of DeArmond's model 210 in appearance, the underside is very different.  The lack of a fixing arrangement and the very narrow flange both suggest that these pickups would be held in place by the pickguard only.  Compare the underside of these pickups with DeArmond's model, seen below:

The DeArmond recessed version of the Model 210 seen here, is fitted with a brass plate that clips into each end of the pickup's frame and has six threaded holes to accommodate the theaded nylon sleeves fitted to each of the pole-pieces.  By contrast, the pickups shown above each have a strip of brass soldered along the edge of the frame to hold the coil former in place.

  This pickup is one type of those manufactured by DeArmond for Ovation's Electric Storm Series of guitars (see that section in this website).  It looks quite similar to the pickup below.

This pickup was fitted in a number of Hofner guitars.  This pickup has 'Hofner' stamped on the front face, but the biggest difference is that all of the DeArmond/Ovation pickups were three-hole fixing, whereas the Hofner has two.  The underside of the pickup is different also.

The pickup shown in this Model 500 Hofner Bass has a bezel which is very similar to that fitted to Ovation's Electric Storm Series of guitars and basses, as seen in the photo above.

    This pickup is from a Kay guitar and is commonly referred to as the 'Speedbump' Model.  The date stamped on the underside of the pickup is shown in the Month/Day/Year format, so '042765' on this pickup means April 27, 1965 (Photo copyright Dangerman1).

Pickups fitted in two makes of European guitars - Hoyer and Klira - look very similar to the recessed version of the DeArmond Model 210, but at the moment of writing, are not conclusively confirmed as such.

Publishable photos of these pickups are not yet available for this site.

The following effects pedals use housings originally designed by and manufactured for DeArmond.  The internal electronics were fitted by the other companies named as shown:
