DeArmond RH-C Model Acoustic Guitar Magnetic Pickup, c. 1957, made in Toledo, Ohio.
The classic round-hole DeArmond, as used by Lightnin' Hopkins and a myriad of others. Still the best raunchy electrification device for the ambitious flat-toppist.
Length is 1 1/2 in. (3.8 cm.), 5 1/2 in. (14 cm.) width. Overall Excellent Condition.
