Serial number 300. Ex coll.: Dennis E. Hartnett, New York.
Arne B. and Jeanne F. Larson Fund, 2004.
This guitar is based on Loar's U. S. Pat. 2,020,557 (filed 1934, awarded 1935), in which electric amplification is combined with an acoustic guitar body. The design offered a player the option of switching between electric and acoustic amplification, or combining both, with metal posts through the bridge that transfers vibrations from the strings to the bar-armature. With the posts raised, the bridge comes in contact with the soundboard for exclusively acoustic amplification; with the posts lowered to contact the metal bar-armature, both acoustic and electric amplification is engaged, and with the posts lowered completely, the bridge is lifted off of the soundboard and supported only by the bar-armature for exclusively electric amplification. The back of the guitar, made from arched spruce, with two f-shaped soundholes, incorporates another of Loar's ideas, covered more extensively in U. S. Pat. 2,046,331 (filed in 1934 but awarded in 1936), to use the back of the instrument as a second soundboard by transferring bridge pressure from the top.
Though Dennis Hartnett took good care of his ViVi-Tone instruments (mandola NMM 10809, mandocello NMM 10810, and this guitar), all three show signs of extensive use. Indentations on the bar-armature and wear to the screw-ends of the posts on the guitar pickup indicate that Hartnett also used the instrument for electric-only amplification, in addition to the electric/acoustic set up in which he left it. Hartnett's guitar is preserved with an amplifier (NMM 10812) by Webster Electric Company of Racine, Wisconsin, and an accompanying foot pedal.
