The rig

Find your
kind of noise.

Choose a manufacturer. Swipe through its pedals. A short description tells you what each effect does before you add it.

From a little overdrive to synth voices, reverse echoes and a swirling phaser. All amps and effects stay available from the start.

Distinct brands. Clear descriptions. One pedal at a time.
Keep playing

A sound you love.
Somewhere to take it.

Save your rig, work on a scale, or find the next idea. The tools are right there when you need them.

Practice

Go at your pace.

Choose exercises or songs. Work to a tempo, or let the exercise wait for your next note.

Practice setup, captured on the Pi.
Presets

Pick up where you left off.

Recall your amp, pedals and settings together. Start with Lemon Glass, Slow Bloom or Iron Rhythm, then make it yours.

Your sounds, one tap away.
Afterglow

A little more
color in your playing.

Kaleidoscopes, connected particles and flocking shapes respond to your guitar. Full-screen art that moves with the music.

One frame from the running kaleidoscope.Every session has its own shape.

Play. Make progress. Earn XP as you play, on any page. Track your playing time, notes captured and sessions.

Your rig stays yours. Your amps, pedals, effects and Afterglow scenes are available from day one.
