The best sound we have got recording this instrument is using a tube mic about 3 feet away from the guitar. Set about in the middle of the instrument. The sound coming off the neck is very important, so by this placement it seems to get the best sound. www.binaryrecordingstudio.com
Really enjoy recording a group like this. Have them sit in a circle and start recording. Mic on each instrument sent to its own track and a stereo mic track. Great players that make a mix down real easy!
