KnobMaster: Guitar Tone AI
Amp settings for any song
Free · In‑App Purchases
Name a song, add your own guitar or bass, amp and pedals, and get knob-by-knob settings for your rig in seconds. Now in 26 languages.
Where do you set your knobs to sound like that song? KnobMaster tells you, for the gear you actually own.
Add your guitar or bass, your amp and your pedals once. Then name a song or describe the sound you're after, and ToneGenie, the AI inside KnobMaster, works out settings for every knob on your rig: gain, EQ, volume, pickup selector, effects.
These are settings for your own gear, not presets for amps you don't have. KnobMaster researches the real controls of each piece of gear, so it works with practice amps, modeling amps, vintage tube amps and pedalboards alike.
