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.


  Truetone guitars were manufactured by CMI/Harmony in Chicago.

  The only example seen to date is identical to the distinctive Harmony guitar Model H78, except for the pickup type and the headsock logo.  Both guitars are fitted with three pickups, three On/Off pickup selector switches and six volume and tone control knobs.

  This guitar was also sold under the Silvertone and Heath/Heathkit brands.

The guitar shown above is a 1965 Silvertone H1454 with the Diamond-grille pickups (photo courtesy Blues Angel Guitars, Pensacola, Florida).  The only difference in specification between this instrument and the Harmony H78 is the pickup type. The Harmony pickup is shown below.  Note the rosewood base, contoured on the underside to provide an accurate fit against the archtop guitar body.
