you jam.jam records. jam tabs.
Two minutes from DI plug-in to riff: sign up, install the engine, pick your interface, play. A Neural Amp Modeler amp on your headphones, any capture from TONE3000, drums on, and everything is recorded. Play for as long as you like. jam records the whole session. Afterwards you crop the good parts for your DAW, and the parts you like become a tab.
plug in. play. keep it.
Plug in, drums on.
Guitar straight into your interface, a NAM amp on your headphones, a click or one of three sampled drum kits. No DAW, no routing, no guessing at levels. Nobody presses record. Play for an hour or longer; the limit is your disk, and jam shows you how much is left.
The whole session, always.
Your dry guitar signal and the drum clock, sample-exact together, all on your machine. Afterwards you crop the good parts and export them: WAV stems with a common start, MIDI and a Reaper project with the tempo map. Open it in your DAW and it is already in time.
The parts you like become a tab.
Mark a part and say where on the neck you played it. jam writes the tab: chords, riffs, single notes. It will get some notes wrong; you fix them in a few clicks, right at the note. Export as Guitar Pro, MusicXML or MIDI.
the drum machine is the ruler.
Drums and recording share one clock inside jam. When you play to its click or one of its three sampled kits, jam knows the bar grid exactly. That is what makes the tab line up, the export land in time, and the good part start on a bar line instead of somewhere in the middle. Jam without drums and you still get everything, with second marks instead of bars.
only what has been measured.
The recording is never wrong; the tab sometimes is. The tab pass has been measured on real guitar takes, so far one guitar and one player. It gets most of a riff right and some notes wrong, which is why every note can be fixed in a click and why jam asks where you played. It is built for riffs, runs, power chords and open chords, not for whole songs with every articulation or for fast solos. And we do not race anyone on amp tone or tracking latency. jam sells that what you played is still there tomorrow, as audio and as a tab.
two minutes, four steps.
Free, no card.
One account for jam and tab. The download button is in the app.
One installer, no admin rights.
The small native engine runs beside the browser. Windows warns once because the beta build is not signed yet; the FAQ says what to click.
Any USB interface with ASIO.
Guitar in, headphones out, dry. A Scarlett Solo is plenty. Choose it on the Rig screen; jam shows the level and warns before you clip.
Amp on, drums on.
Pick a capture: eight ship with jam, from a '62 Princeton to an Engl Powerball, plus a cabinet. The input trim sits at −18 dB by default, so clean stays clean. Thousands more are on TONE3000, free, see below. Pick a kit and a tempo, or no drums at all. From here on, everything you play is kept.
Windows 10 or 11 only. No Mac build yet; we say so rather than promise one. No microphone mode, no phone.
any NAM amp. from TONE3000, or your own.
jam plays Neural Amp Modeler captures, the open .nam format the whole capture community shares. TONE3000 has thousands of them, most of them free: download the file, drop it onto the Rig screen, and it is loaded. Eight of them ship with jam, licensed CC0 or CC BY, credited by name. Amp captures, pedal captures in front, a cabinet impulse response behind, a noise gate. The engine behind it is amp, part of the plan.
native, on your machine.
The amp does not run in the browser. It runs in the native engine at your interface’s driver latency, so it feels like an amp, not like a web page. The amp is on your headphones only; the recording stays dry, so you can change the sound tomorrow, or in your DAW.
jam is in a beta test.
jam works and is a work in progress; we are finishing it first. Sign up, download the Windows build, play. Everything is free until 23 December 2026, no card, same account as tab. In return we want to hear what broke and what you missed; the tab in particular will be wrong sometimes, and we want to know where. Bring an audio interface; there is no Mac build yet.
