Play better · Build your own
Everything you
need, nothing
you don't.
A tuner that reads to a single cent. A metronome with a drummer behind it. Every chord on the neck. And, on the other side of the site, the whole process of building an electric guitar from a rough plank to a working instrument.

The tools
See all →Five browser tools built for practice, not for show. Every one of them works on a phone, works offline once loaded, and never asks you to sign up.
Chromatic tuner
Forty-two tunings from standard to eight-string drop E. Reference pitch from 415 to 466 Hz. Reads to one cent, and won't jump an octave on your low B.
TimeMetronome & drum beats
Nineteen grooves — shuffle, half-time shuffle, 12/8 blues, train beat, 7/8 — with an editable step grid, swing control and tap tempo.
HarmonyChord library
Pick a root, get every chord built on it, sorted by family. Fingerings, the notes in each voicing, and a button to hear it strummed.
FretboardScales & fretboard
Any scale or mode drawn on the neck, with the intervals labelled, the five box positions marked, and playback so you can hear what you're looking at.
EarTuning by ear
The fifth-fret method step by step, the harmonic and octave checks, a beat-frequency lab, and the strange political history of A = 440 Hz.
PracticeLearn & practise
Routines that actually work, why slow practice wins, and how to stop plateauing after your first two years.
Build your own
The build section →The other half of the site: a free 21-hour course covering every stage of building an electric guitar, plus the calculators you need to get the numbers right before you cut.
Fret position calculator
Slot positions to the thousandth of an inch for any scale length, including multiscale fanned frets. Print it and use it as a template.
CalculatorString tension calculator
Work out what a set will actually pull at your scale length and tuning, before you find out the hard way that your down-tuned build is a wet noodle.
ReferenceWiring & electronics
What pot values, capacitors and switch types actually do to your tone, and how to pick them without cargo-culting a forum post from 2006.
