Genre — the whole sound at once

Classic Rock

A Precision played with a pick into a tube head and an 8×10 cabinet, steady eighths under the guitar chords.

Press a string at a fret to play a note. Drag across the string to bend, along it to slide. Arrow keys move a cursor over the neck, Enter plays the note under it.

A phone speaker does not play a bass's fundamental: this mode adds its harmonics so the notes come through. Turn it off on headphones or a speaker.

The same chain works with a real bass guitar: connect it through an audio interface with an instrument input or a USB cable. The tuner and noise gate are set for the low strings.

Listen in wired headphones: from speakers the sound comes back into the microphone and howls, and Bluetooth adds tens of milliseconds of delay.

Features

A bass string, not a guitar string
String stiffness and the decay of every overtone are fitted to measurements of real bass guitar recordings: the fundamental rings long, the low mids die fast. Fingers and a pick set the string going differently.
From blues to death metal
17 genres — blues, soul, funk, disco, reggae, jazz, rock, punk, grunge, post-punk, heavy, thrash, doom, modern and death metal: each with its own bass, technique, tuning, amp, cabinet and band.
A band: drums and electric guitar
The drummer plays the genre's groove — shuffle, one drop, blast beat, gallop — and the rhythm guitar plays the song's chords: it is the site's electric guitar with its amp in the matching genre.
Are you on the beat
While the band plays, every note is measured against its grid: how far ahead of or behind the beat, and the share of notes tighter than 25 ms. Bass players learn this with the kick drum — here you see it at once.
Audible even on a phone speaker
A phone speaker does not reproduce a bass's fundamental — 31–100 Hz. The Phone speaker mode adds its harmonics: on a speaker model the low notes get 24–34 dB louder and the pitch heard stays the same.
Record to WAV, MP3 and MIDI
A take keeps your playing and the band's: change the genre or the knobs and download the same take with a new sound. The MIDI file has separate bass and guitar tracks.

Bass guitar online FAQ

Why can I barely hear the bass on my phone, and what does Phone speaker do?

A small phone speaker barely plays anything under 300–500 Hz, while a bass's fundamental is 31–100 Hz. The mode takes the bass's low end, makes harmonics above 250 Hz from it and blends them in — your ear rebuilds the missing fundamental. It starts on for a phone; turn it off on headphones or a speaker. It never goes into the recorded file.

What is the difference between fingers and a pick?

A fingertip is a soft pad: the string rolls off it over milliseconds, the attack is round and the tone thick — that is how blues, soul, reggae, jazz and funk are played. A pick slips off the string in under a tenth of a millisecond: a click on the attack and a bright top that punk, thrash and death metal are built on. The Fingers / Pick switch sits next to the note buttons; each genre picks its own.

How does the "on the beat" meter work?

While the band plays, every note you play is compared with its grid — sixteenths, or triplets in a shuffle. The meter shows the average offset of your last notes — ahead of or behind the beat and by how many milliseconds — and the share of notes tighter than 25 ms. Your note and the band reach the speakers by the same path, so the audio latency does not skew the comparison.

Can I play a five-string bass and low tunings?

Yes: a five-string with a low B, the B E A D G and Drop A tunings, and for four strings Drop D, D standard, Drop C and B E A D. The five-string is picked automatically when a tuning needs five strings; the modern metal and death metal genres start on it.

How do I connect and tune a real bass guitar?

Connect the bass through an audio interface with an instrument input or a USB cable and open Plug in your own bass: it goes through the same amp, and the built-in tuner hears the low B too. To tune by your phone's microphone there is the Guitar and Bass Tuner — it has 13 bass tunings.

Which guitar plays in the band?

The site's electric guitar in the matching genre: a superstrat in B standard through high gain for death metal, a clean single coil for reggae, an auto-wah for funk. It plays the song's chords the way the genre does: a skank on the offbeats in reggae, tremolo under the blast beat, four to the bar in jazz. The Guitar button in the band panel turns it off.
