Fretboard Distillery is a free guitar transposition tool built for how guitarists actually work. Paste in any chord sheet, pick the chord shapes your fingers know best, set the key you need, and the tool calculates your capo position automatically. It includes Nashville Number System notation, simplified worship chord voicings with fretboard diagrams, a chord position editor for precise alignment, and a full-screen performance mode with auto-scroll and metronome. No subscription needed.
