i was reading throughthe big book of bluegrass and came across a picture of Sonny Osbourn holding a six string banjo,but not like the deering guitar type. it looked like a normal vega 5-string with an additional bass string between the low D and high G. has anyone ever seen, played, or know how to get there hands on one these? if so, how is the sixth string tuned? I'm thinking low A or B. definitely looked like a fun one to play.
thanks,unclenort
