The Integrated Side Dot Tuner (ISD Tuner) is a patent pending innovation available exclusively from Schenk Guitars.  This is the coolest guitar innovation since the soundhole!

Using fiber optic technology and custom electronics, the ISD Tuner is a completely concealed chromatic tuner.  The uniqueness of the ISD Tuner is how it illuminates the 15th, 17th, and 19th fretboard side dots to indicate the proper string pitch.

With a cool factor off the charts, the ISD Tuner is becoming a standard choice for all custom guitar orders!
