Tonedevil S-12 model has become the new industry standard harp guitar for pro performers and hobbyists alike. Customizing the design slightly allows for additional strings and the different tone wood combinations can nicely augment its brilliant sound. Super treble strings make a triad possible in the higher octave you can’t get on a standard 6-string neck. And the 12-string guitar with 6 sub harp strings (S-18 model) is coveted as every finger-picker’s dream. As always our passive piezo contact pickup system is factory installed on all instruments.
