Just when you think you know everything, along comes a new piece of
information. I used to believe that National Resophonic got into electric
mandolins a few years after the other big makers. That was before I
started stumbling across instruments like the one above, dated as early as 1934. That
would make National the second company to produce an electric mandolin—three
years after
Rickenbacker, but two years
before
Gibson and
Vega.
How many of these instruments were produced I don't know.
I do know that in the late
1930s, the company introduced its Silvo pickup, which was mounted in a
flat, round, black plate that replaced the resonator cover on a National
mandolin or guitar. The resonator cone was also left out of instruments
with Silvos. The result is pictured below left. Such instruments appeared
in the National catalog for a couple of years; players
could also send their Nationals back to the factory to be retrofitted.
Apparently, Silvos were not a
big hit; National soon abandoned them and started designing other electric
guitars. (They later made some more wood-bodied acoustic/electric
mandolins under the
Supro brand.)
There are still a few Silvos around in playable condition. The
late
Mark Heard owned one, and recorded a
fantastic album with it called
Satellite Sky. I once got the chance
to play his, and after several years of searching, wheeling, and dealing,
I've managed to get one for myself. Now if only I could play it like Mark
