This one shows a strobe, the display serious players use because it reads the direction and speed of a string at a glance. Flat, the bands drift left. Sharp, they drift right. In tune, they stand still. ## Play a string The tuner works out which string you played by itself, names it, and says how far off it is: "Low E, 32 cents flat. Tighten the peg slowly." Hold it in tune and that peg's lamp lights. Tune all six and the whole headstock lights up. To work on one string only, click its peg. Click it again to go back to any string. ## Hear it first Clicking a peg also plays that string. The reference note is a plucked string made on your PC at the exact pitch, not a recording, so it is never slightly off. Prefer to tune by ear? Play every open string in turn, lowest first. A pure tone is there too, for anyone who finds the overtones distracting. While a reference note plays, the tuner stops listening, so it never tunes to its own speaker. ## Accurate to within a cent A cent is a hundredth of a semitone. Most people cannot hear a difference smaller than about five. The tuner was checked against hundreds of recorded guitar and bass notes, including the low strings that trip up cheaper tuners by reading them an octave too high. A chart of the last eight seconds shows how steady the string really is, so you can watch it hold instead of taking a needle's word for it. ## Guitar, bass and ukulele 16 tunings: The headstock is drawn for whichever you choose, three pegs a side for a guitar and the right count for a bass or ukulele. A capo from the 1st to the 7th fret moves every target up to match. Any-note mode reads every note rather than the open strings, for slide, other instruments or checking intonation up the neck. - Guitar: standard, half step down, whole step down, Drop D, Drop C, DADGAD, open G, open D, open E and open C - Bass: 4-string, 4-string drop D and 5-string - Ukulele: standard high G, low G and baritone ## Make it yours - Concert pitch from 430 to 450 Hz, for bands and recordings not at A440 - In tune within 1, 2, 3 or 5 cents: tight for the studio, forgiving in a noisy room - A sensitivity setting, so room noise does not move the strobe - Sharps or flats for note names - A left-handed headstock - Always on top, over recording software or a lesson video - Any microphone or audio interface, with a live input level - Number keys pick a string, P plays it, A goes back to any string ## Private by design The microphone is used only while the tuner is open, and listening pauses when it is minimized. Nothing you play is recorded or uploaded. There is no account, no ads, and it works with no connection at all. ## Features - A strobe that drifts left when a string is flat, right when it is sharp, and stands still when it is in tune - Accurate to within a cent on a held note - Finds the string you play by itself, or click a peg to tune one string on its own - Each peg lights up once its string holds in tune - Hear any string as a plucked-string reference note, made on your PC at the exact pitch - Play every open string in turn and tune by ear - 10 guitar tunings: standard, half and whole step down, Drop D, Drop C, DADGAD and open G, D, E and C - Bass: 4-string, 4-string drop D and 5-string - Ukulele: standard high G, low G and baritone - A capo from the 1st to the 7th fret - Any-note mode for slide, other instruments and checking intonation - A chart of the last 8 seconds, to see how steady a string really is - Concert pitch from 430 to 450 Hz - Choose how close counts as in tune: 1, 2, 3 or 5 cents - Pick any microphone or audio interface, with a live input level - A left-handed headstock - Always on top, over recording software or a lesson video - Keyboard shortcuts: number keys pick a string, P plays it - Light and dark themes - Works offline.
