Surprise ~ My friend brought the Orpheum banjo over today. I started tuning the thing and promptly broke the first string. Thought it looked a bit big for a tenor so I compared it to my tenor and the neck was somewhat longer ~ 22 frets to be exact. Seems the banjo is a plectrum rather than a tenor. Actually this was the first one I'd ever had in my hands so I looked up the tuning and found it was tuned the same way as C tuning on the 5 string banjo. A whole new ball of wax. The peg head inlays were a bit more fancy than on the regular tenor.
    Seems the plectrum banjo's ranged a bit in size from 22 to 26 frets. The earlier ones tended to have the lower number.
