The DeArmond Model 2000 pickup

 

Photos above show the original version of the DeArmond Model 2000 guitar pickup.  The Patent application was filed on May 10, 1950 by Harry DeArmond and was granted on September 30, 1952
under No. 2,612,072.  The first picture shows the six magnetic pole-pieces and the six screws for adjusting the poles' height.  The second picture shows the underside of the pickup, with the brass rings crimped to the ends of the pole-pieces and the six screws threaded into the brass rings.

This new pickup design was a radical improvement on previous models as it allowed for adjustment of the height of each individual pole-piece in minutes without removing any of the strings and without the need for special tools.  The offset location of the adjustment screws was copied by other pickup manufacturers.  The original patent description referred to fixing the threaded brass spring retainers using solder and that may have been so initially, but apart from just one soldered example seen, all others have been crimped to the magnets using pressure   Perhaps the solder temperature may have partially demagnetised the pole-pieces.

The Model 2000 first appeared in Gretsch's 1949 catalog and was referred to as the referred to as the 'Dynasonic' & 'Fidelatone' by them.  It was available in only one height initially , measuring 7/16" ( 11 mm.) from flange to top of pickup, to suit the neck position.  Where the pickup was located at the bridge, one or more packing pieces were stacked under the pickup.  Finish options were chrome with black coil former or gold-plated with white coil former.  The bridge version, called Model 2000-T, with a metal frame height of 9/16" ( 14.3 mm.)from flange to top of pickup appeared some years later.


 

A number of variations on the basic Model 2000 shape were produced over the years.  The versions above with overlapping coil formers were fitted in Premier guitars manufactured by the New York-based Multivox Corporation.  Note the two different heights of the pickups in the right-hand photo (left-hand photo above is courtesy of Artstream, right-hand photo is courtesy of Southside Guitars).
The white pickup version above, but without the chromed brass frame, was used by Les Paul while developing the Les Paul guitar and is clearly seen in many photographs of his instruments from that period.


   

CF Martin used several versions of the Model 2000 pickup in their F-series of archtop and flat-top electric instruments.  The asymmetrical opening in the top of the pickup is a common characteristic of all of CF Martin's DeArmond pickups.  The archtop model shown above on the left was supplied in two heights for neck or bridge mounting (photo courtesy of Jim Washburn).  DeArmond's in-house reference for these pickups was MA-5.  In 1983, Guild produced a Duane Eddy Model DE-500 guitar fitted with two gold-plated pickups on white plastic bases (photo courtesy of Kevin Viner-Plumley, retrofrets@blueyonder.co.uk).  CF Martin fitted DeArmond pickups in their model D00-18 acoustic flat-top guitars.  The photo shows the arrangement in the D18-E and D28-E guitars (photo courtesy ferrug123).  One example seen has both pickups fitted at the soundhole.  The 00-18E has one pickup fitted at the fingerboard.


   

These photos show the Model 2000 variant as fitted in Standel/Harptone guitars models 430, 510-C(for Cherry, seen above), 520, 550 and 811.  The pickup's plastic bezel is black/white/black, bevelled, with three holes for the pickup itself which is fixed to the bezel with three fixing/height adjustment screws (pickup photos courtesy of Keith Myers, vintageguitarspecialist@gmail.com.  Guitar photo courtesy of Stevie B's, Clearwater, Florida).



  

This pickup was fitted in an Epiphone Emperor single-pickup archtop.  The missing chrome trim-ring is as shown in the left-hand photo below.

The pickup on the left, above, was fitted in the Kustom Model K200 guitar.  These came in two different heights as with the original Model 2000, but the pole-piece spacing was the same for both pickups.  The pickup on the righ is shown installed in an Italian-made a Rokes XII guitar,  The pickup's bezel-fixing screwholes are used to secure this pickup to the pickguard.
