support@knobmastr.comOpen the Profile tab and tap "My Gear". From there you can add your guitars, basses, amps, and pedals. KnobMaster uses this information to tailor every tone recommendation to your specific equipment.
Make sure you have at least one instrument and one amp added to your gear list. Tone generation requires both to produce accurate knob settings.
Precision Mode is a Pro feature that lets you upload an audio file or track. KnobMaster separates the guitar or bass from the mix and analyzes the tone directly, giving you more accurate settings than standard mode.
