Been playing some Kingston Trio for a little variety of my normal Scruggs style. I have one banjo I tune to open E or maybe even D (strings start getting floppy at D) but would match my attempts to sing a little better.
After watching some youtubes beginning to wonder why long necks if they usually capoed up 3 to 8 frets? I think I may hold off buying the $6,299 long neck Deering for awhile (lol).
By using a longneck, two tunings, and a capo, Pete and the other folkies had access to all keys almost instantly. Remember, these people were singers, not subject to the key limitation of fiddle tunes.
I love playing my long neck banjo...personal taste. I play a regular scale open back as well. There are great sounding vintage longnecks for less, sometimes far less, than $1000: Gibson RB-175, ODE Model 33, Vega Folklore each has a different tone. Then there's the not as playable Silvertone, Gretsch made Bacon, the occasional Christie, and others. But, yep singing in a key within one's range was the reason Pete Seeger paid John D'Angelico to graft three more frets onto a neck attached to an old Tubaphone pot. But, it's also just a great sound for some.
I just purchased the George Grove "Banjo Arrangements of the Kingston Trio". I hope it has the tabs (bought used), but I don't really like learning by dvd. I do know Scruggs style of several of the songs, so may be able to change styles by ear for a little variety. I fixed up a Leo Fender banjo awhile back with a Tony Pass woodie rim that sounds pretty good. Might purchase a long neck for it if needed.
