John, I play a restored Weymann Plectrum (1930) Banjo......with, strangely enough..."Chicago Tuning".....same as top 4 guitar, but the technique is totally different.....& chord voicings too.RE the 'Celtic side'.....I also use the Banjo in some shows to play Jigs & Reels.....we have to keep the Scottish Standard flying! .....meanwhile....have to get my 'Jazz Head' on again for Thursday! Regards, Joe G.
