Guitar Tools & Calculators
Free, practical tools for players — dial in your tone, work out string and setup choices, plan your practice, and make smarter gear decisions, whatever you play.
String Tension Calculator
Work out the static tension a string pulls at from its unit weight, scale length, and target pitch — using the standard D'Addario formula — to balance a set or plan an alternate tuning
Guitar Setup Calculator
Turn a target 12th-fret action into an exact saddle height change — since the saddle moves the string twice as much at the 12th fret — and see whether to raise or lower it
Practice Schedule Builder
Split a fixed practice session across the areas you want to work on — technique, repertoire, theory, improv — allocating minutes proportionally to the weight you give each
BPM Tempo Trainer
Build a speed ladder from a starting tempo up to your target in fixed steps, with the minutes per step, total time, and the quarter-note length in milliseconds at the goal tempo
Fretboard Note Trainer
Name the note at any fret on any string — pick an open string and a fret and see the note and how many octaves above the open string it sounds, to learn the fretboard cold
Chord Progression Generator
Turn Roman numerals into real chords in any major key — enter a key and a progression like I-V-vi-IV and get the diatonic chord names, with correct major, minor, and diminished qualities
