The major part of DeArmond's pickups range catered for guitars and electric basses, but they also produced pickups for a variety of other instruments including banjo, mandolin, autoharp, bass viol, ukulele and piano as shown below:
Attachable pickup for banjo. The pickup's mounting bracket is bolted to the reinforcing bar located in line with the neck, under the instrument's bridge. This particular pickup is the 2nd version of Model 76.
Attachable pickup for archtop mandolin. Early model with split black plastic insert, black chicken-head knob and overlapping lid on volume pot enclosure. Metalwork finished in chrome.
This Harmony mandolin, Model H35, was fitted with an S-grille soapbar pickup in a black plastic bezel. The pickup would appear to be recessed, but is not. This particular pickup/bezel combination was not fitted to any other Harmony instrument.
Model 500 Attachable pickup for archtop mandolin, metalwork finished in choice of chrome, black or white. This is the later model with single black plastic insert
This gold-plated Model 500 fitted to this Kentucky Mandolin is one of a limited edition produced to order. It was designed for
screwfixing direct to the guitar's pickguard, and terminated in
DeArmond's standard inline mini jack-socket. The company was flexible
and accepted orders for products such as this providing the quantity was
sufficient. In some instances that quantity could be as low as 50
items. A similar variation on the Model 1100 guitar pickup finished in
gold was also produced.
Model 700 Attachable pickup with integral volume controller (later gray knob, embossed 'CTL') for violin, metalwork finished in chrome
Attachable pickup with integral volume controller (earlier black milled-edge knob) for violin, metalwork finished in white (transducer head) and black (attachment arm).

Model Stringtone bridge-mounting tuning changer for steel guitar. The unit has a central camshaft that may be rotated by the lever shown. The instrument's strings pass over this camshaft and as they come in contact with the projections on that shaft, their pitch is altered.
The text of the promotional literature is as follows:Change tunings without removing bar from strings. Easily and quickly installed by anyone. Compact, attractive. Change tunungs with a flick of the lever. Will last a lifetime. Most useful accessory for the Hawaiian guitar since the advent of the electric guitar. Light in weight - does away with lugging around a heavy double neck or 3 neck guitar. Gives you instantly and accurately three tunings (A, E and c# Minor) at touch of finger. Can be attached to most Hawaiian, electric or steel guitars (wood, metal or plastic). Gives new and thrilling chord voicings to instrument with convenience of three necks in one.'
