Here's a unique instrument, seems to be a blend of lute and banjo. It is made to a baritone scale and uses the common DoGBonE D-G-B-E tuning except that it also has a high g drone string. I haven't come across Kristoffer's videos or instruments or videos before but quickly recognized the Swedish accent. I think that the Ash wood he uses is common to Scandinavia.
This banjola is a gift for his brother. So I do hope that he makes another to share some more videos with us. Tack så mycket Kristoffer.
