DeArmond numbered products

Every DeArmond product – musical instrument pickups, effects units, amplifiers and spare parts – sold to the public through music outlets and distributors was given a specific reference number.  These items are listed below, using DeArmond’s own numbering system. 

The model numbers for other pickups produced for musical instrument manufacturers including D’Angelico, Eko, Epiphone, Emmons, Fender, Gretsch, Bacon Belmont, Guild, CMI (Chicago Musical Instruments), producers of  Harmony, Airline, Alden, Barclay, Heathkit, Holiday, Monterey, Regal, Sears-Roebuck, Silvertone, Truetone and others, Hofner, Kustom, Levin, CF Martin, Messenger, Micro-Frets, Ovation, Premier, Rickenbacker and Standel (including Harptone and Koontz) are, with very few exceptions, not generally known.  Where known, these numbers are included below.

DeArmond did not market any fretted Bass pickups under their own name.

Two pickups listed below, models 6700 and 6701, were packaged and marketed as Harmony products in Harmony catalogs, but not in DeArmond’s catalogs or price lists.

The Model 6812, a four-scroll (moustache) pickup with a white plastic bezel, was fitted in many Harmony guitars.  Another pickup listed below, the much rarer Model 6811, appears identical to the 6812 above.  The only difference may be in the height of the white plastic bezel.  Four different heights for the bezel have been recorded so far.  These pickups are so named because some existing examples have that number stamped on their underside, in addition to the company name.

Two pickups listed below, Models FP-6 and FP-12, were packaged and marketed as  Fender products.  One version has the edgewise volume and tone controls visible through slots in the pickup’s chrome cover.  The other version has the edgewise volume and tone controls visible  the pickup’s chrome cover.  However, which is which has not yet been clarified.

Some re-sellers who produced their own catalogs used their own numbers when marketing DeArmond pickups.  For example, Kay’s 1963 catalog shows twelve DeArmond products, including the Model 1000, which is shown as item No. 47385F2650.

Model 40 Attachable pickup, chrome-finished with no visible pole-pieces and four black-filled slots, for flat-top roundhole guitar.  This is a basic bar magnet pickup, similar to the plain ‘Hershey Bar’ type, positioned within the soundhole and is screwfixed to the front face of the guitar through two tabs (Ouch!). The pickup’s top cover is rivet-fixed through the bar magnet to the pickup’s steel baseplate.  A separate V & T (Volume & Tone) open-backed controls box, hardwired to the pickup head, is screwfixed directly into the guitar’s top (Ouch again!), terminating in a mini-jack socket.  The example shown above has two black cylindrical, conical knobs.

Model 41 Attachable chrome pickup with no visible pole-pieces and four black-filled slots, for archtop or flat-top guitar.  This is a basic bar magnet pickup, similar to the plain ‘Hershey Bar’ type.  It has an integral chrome bezel and is screwfixed to the front face of the guitar.  This bezel is designed to follow the contour of the archtop body, or sit flat (see photo No. 3 of 3 above).  A separate V & T (Volume & Tone) controls box, hardwired to the pickup head, is screwfixed directly into the guitar’s top, terminating in a mini-jack socket.

Model 55 Attachable chrome pickup with four black-filled slots and six individually adjustable pole-pieces, for archtop guitar with separate controls box, both screwfixed directly into the guitar’s top.  The fixing arrangement is as for Model 41 above.  A separate V & T (Volume & Tone) controls box, hardwired to the pickup head, is screwfixed directly into the guitar’s top, terminating in a mini-jack socket.

Model 55-FB-12 Set of two Model 55 pickups with wiring harness including three pots (Volume, Tone and Blender controls – no switch) and output jack socket.  The pots were designed to be flush-mounted into the guitar’s top, with all wiring concealed. 

The pickup as shown above – chrome bezel, six adjustable pole-pieces; two rivets holding bezel to coil housing; white top area – did not go into production.  The illustration above is from DeArmond’s 1965 catalog.

Model 55-FB-7 Model 55 pickup with wiring harness including separate V & T controls and output jack socket, as manufactured.  The V & T controls were designed to be flush-mounted into the guitar’s top, with all wiring concealed.

Model 56 Attachable chrome pickup with four black-filled slots and individual pole-pieces, for flat-top roundhole guitar with separate V & T controls box, both screwfixed directly into the guitar’s top, terminating in a mini-jack socket.

Model 60 Tremolo pedal, without serial number (120 Volts electrical supply required).  This example has the same knobs as shown in Rowe-DeArmond’s 1948 Leaflet.

Model 60A Tremolo pedal, with serial number (120 Volts electrical supply required)

Model 60B Tremolo pedal (120 Volts electrical supply required)

Model 112T CF Martin vacuum tube amp (as DeArmond R15T amp)

Model 130 Attachable black humbucker, roundhole flat-top guitar

Model 200 – There is no such DeArmond pickup.  DeArmond produced the model 2000 pickup as used by Gretsch (who named it the Dynasonic Fidela-Tone), Guild, Hofner, Levin, Premier and many others.  The Model 2000 was referred to incorrectly as a 200 in some discussion groups and as a result, that name has unfortunately gained undue credence.

Model 210 Attachable chrome pickup with adjustable pole-pieces and recessed edgewise volume controller for roundhole flat-top guitar.  One example of this pickup has been seen with a self-adhesive plastic woodgrain finish.

Model 210-C as model 210 but with side-mounting jack and quick-disconnect cable

Model 220 Attachable chrome humbucker, 1st version, with integral volume controller, for roundhole flat-top guitar.  The two fixing arms on the pole-pieces side are spring-loaded and the third arm has a collet which is tightened manually to set the pickup in position.

This was Rowe DeArmond’s first humbucker and at 2.92″ x 1.517″ (74.18 x 37.54 mm.) has different dimensions than other humbuckers.  The company’s subsequent humbuckers – Models 2200, 2300 and 2400 – were all slightly wider and longer, at 2.756″ x 1.549″ (70.00 x 39.28mm.)  It should be remembered that this pickup was produced at a time when ‘standard dimensions’ for these items did not exist

Model 220-C as model 220 above but with side-mounting jack and quick-disconnect cable.

Model 220 Attachable chrome humbucker, 2nd version, with integral volume controller, for roundhole flat-top guitar.  Available in chrome or gold finish.  The two fixing arms on the pole-pieces side are as before, but the collet was replaced by a spring-loaded arm which makes installation and removal easier.

Model 6700 Attachable chrome S-grille soapbar with gold insert, for flat-top guitar, with separate V & T controls box.  The difference between this pickup and Model 6701 is that the fixing bracket is flat in the 6700, whereas the bracket is offset downwards in the 6701 to clear the strings.

 

Model 6701 Attachable chrome S-grille soapbar with gold insert, for archtop guitar, with separate V & T controls box.  This pickup differs from the Model 6701 above, in having no semi-recessing offset in the long fixing bracket.  It was designed to be screwed to the top of the guitar body.

 

Models 6811 and 6812 pickups

Models 6811 pickup underside

Models 6812 pickup underside

Models 6811 and 6812 Four-scroll chrome guitar pickup with white bezel, supplied only to CMI (Chicago Musical Instruments), for their range of Harmony guitars.  The only difference between the quite rare 6811 and the more common 6812 may be a difference in the height of the white plastic bezel.  Four different heights for the bezel have been recorded so far.  These pickups are so named because most existing examples – a four-scroll (moustache) pickup with a white plastic bezel – have this number stamped on their underside.  The long sides of these pickups are either flat or slightly convex on their longer side, to allow for the curvature of archtop instruments.  A separate section of this site deals with pickup bezels and bases.

 

390-00070-90 There is also an optional short offset rod used to fit the Model 1000 Rhythm Chief and model 1100 directly to the guitar’s neck.  This rod can also be used to attach the FH series to the neck.  Although this item was first produced in the 1950s, the first time it appeared as a separate item in DeArmond’s sales literature is in about 1975, in their orange catalog.  The item numbers given are 390-00070-90 for chrome and 390-00071-90 for gold.

Photo 1: Three pressure rod and bracket assemblies together, for comparison.

Photo 2: This bracket (at top in Photo 1 above) is an early version for FH and FHC guitar pickups.  Two round-head slotted screws are screwed into threaded bracket which is secured by the two slotted nuts shown.

Photo 3: This bracket (middle item in Photo 1 above), Part No. ML-49, is final version of FH, FHC-B and FHC-C guitar pickups.  The two milled-edge thumb screws hold the clamping strip in place.

Photo 4: This bracket (bottom item in Photo 1 above), ML-51, is for Model 500 Mandolin pickup.  A second version of this bracket with a slightly longer pressure rod is used with Model 400 Tenor guitar pickup.

Notes: The rod bracket assemblies nos. ML-49 and ML-51 listed above, each comprise a rod (referred to as a ‘pressure rod’ by DeArmond), with a threaded tab attached, and a separate punched metal strip with two small thumbscrews.

The pointed end of the rod is inserted in the pickup head and the tab on the other end of the rod is clamped to the instrument’s strings behind the bridge.

The diameter of the ML-49‘s (Archtop pickups FH, FHC, FHC-B, FHC-C) rod at 1/8″ (3.175mm.) is greater than the ML-51‘s (Tenor guitar model 400 and Mandolin model 500) rod at 3/32″ (0.093mm.) so they are not interchangeable.

In DeArmond’s literature, the rod assembly is sometimes referred to as pressure rod or tension rod and master clamp.  It is often referred to as a ‘Monkey on a stick’ by collectors and users, but never as such by DeArmond.

There is also an optional short offset rod used to fit the Model 1000 Rhythm Chief and model 1100 directly to the guitar’s neck.  This rod can also be used to attach the FH series to the neck.  Although this item was first produced in the 1950s, the first time it appeared as a separate item in DeArmond’s sales literature is in about 1975, in their orange catalog.  The item numbers given to it are 390-00070-90 for chrome and 390-00071-90 for gold.
