These string sets have been formulated by Shane Speal, King of the Cigar Box Guitar, based on his 25 years of experience of what works for cigar box guitars on stage. This is Shane's electric set, for when your instrument hasa magnetic pickup. Each string pack also includes alternate tunings that you can try with these strings. String specs: #1 - .046" Nickel Wound (Low G); #2 - .032" Nickel Wound (Middle D); #3 - .022" Nickel Wound (Middle G); For best results with reaching the desired tuning, these should be used on a CBG that has a scale length (the length from the nut to the bridge) in the 23-27" range. Much longer or shorter than that and the strings will either be too loose and sloppy, or so tight that they break before they reach the pitch.
