Hush Amp

Plug a guitar into the audio interface or guitar adapter you already own and play through a real-sounding amp, with pedals, a tuner, and a coach that names your chords.

For Mac (macOS 14 or later), iPhone and iPad (iOS 26 or later). US$2.99 once, for all three: no account, no subscription. Coming soon to the App Store.

What it does

The amp. Six voices, from Clean and Chime through Tweed and Crunch to Lead and Modern. Five speaker cabinets, or your own impulse response file. A tuner, always on.
The pedal board. Six slots, three before the amp and three after, then delay and three reverbs. Twenty-four guitar presets.
The Coach. Strum a chord and it names it, then draws easier ways to play it, like Fmaj7 for an F barre chord. It guesses your capo.
The Ear. Play a song and it tells you the key, the tempo and the chords bar by bar. On a Mac it can listen to what the Mac plays; on iPhone and iPad, play the song out loud nearby or into the input.
Drums too. Switch to Drums for a drum channel with thirty-nine presets.

What you need

An audio interface with an instrument input, or a guitar adapter. On iPhone and iPad, one that plugs into USB-C.
Wired headphones, or speakers on the interface's outputs. Bluetooth headphones lag too much to play through.
Turn the interface's direct monitor off, or you hear the dry guitar and the amp together.

Privacy

Nothing is recorded and nothing leaves your device. The App Store version makes no network connection, has no account and collects no data. Read the full Hush Amp privacy policy.

I hear nothing. Check the input is the interface or adapter, and that Hush Amp is allowed the microphone in Settings, Privacy and Security, Microphone. Your platform treats an interface input as a microphone.
I hear the guitar twice. Turn off the interface's direct monitor.
It crackles. Pick a larger buffer, such as Normal or Safe.
The sound lags. Use wired headphones or the interface's outputs, and a smaller buffer.
