The most complete virtual guitar online: four instruments, every key, real chord shapes, songs, a backing band and recording, all free in one place.

• Steel-string acoustic, classic guitar, electric and four-string bass, each built from recorded samples. Pick a recording for the acoustic (Warm, Bright or Mellow) and the classic (Natural or Concert), and presets for the electric, from Clean to Crunch, Classic Rock, Metal, Lead and Ambient.

• Pick any of the 24 major and minor keys and the chord keys fill with the chords that fit it: the main chords, sevenths, and sus, add9 or sus2 colors. Edit puts any chord you type, like F#m7 or Dsus2, on a key.

• While a chord rings, the neck shows finger numbers, barres, muted strings and the capo. Standard is the shape most players learn first, Easy swaps a barre chord for a smaller shape, and Up plays the same chord higher up the neck.

• 51 songs and classical pieces come set up to play, from Wonderwall and Hotel California to Canon in D. Slow them to 20%, lead their chords from the keys, or play along on your own guitar.

• 14 everyday strums from Steady downs and the pop staple D DU U DU to shuffle and 6/8, 4 styles (reggae, funk and country), 26 more rhythms drawn from real songs, and 12 picking patterns like Travis and classical p-i-m-a. Choose one and you hear it straight away.

• Drums, bass and strings that follow your chords: 15 drum styles, including rock, funk, reggae, bossa nova and cajon, and 25 bass lines. The Band switch next to Play turns them on. Tempo goes from 10 to 220 BPM, with a metronome.

• Paste a song from a chord site or as ChordPro text, pick a strum, and Guitoro plays it with the band. Write "x2" to repeat a line or a part. Lyrics are left out, and your songs stay in your browser.

• Play single notes and melodies on the neck from the computer keyboard, with hammer-ons, pull-offs, bends and vibrato.

• Overdrive, distortion and fuzz on the electric, plus bass, mid and treble, room or hall reverb, and delay on every instrument.

• 10 tunings, from Standard, Drop D and half step down to DADGAD and Open G, D and E, a capo up to fret 10, and a left-handed guitar.

• Record takes of up to 10 minutes with the band, replay them and save them as WAV or a small compressed file. Takes stay in your browser.

• A free guitar tuner that listens through your microphone, with pages for drop D, open tunings, the bass and the ukulele.
