Learn your fretboard with the SPEKTRUM Creations Concept teaching method. A great way to master your knowledge of the fretboard by using the colors to identify the notes, with this simple concept where A–B–C–D–E–F–G are always the same and as long as you’re in standard tuning( E–A–D–G–B–E ), you’re good to go.
Unlike other teaching tools, the SPEKTRUM Creations Concept design fills in all of the fingerboard for a truly unique look.
