Distortion pedals in Logic Pro for iPad
Candy Fuzz
Candy Fuzz is a bright, “nasty” distortion effect.

Drive knob: Set the input gain.
Level knob: Set the effect output volume.
Double Dragon
Double Dragon is a deluxe distortion effect.

Drive knob: Set the amount of saturation applied to the input signal.
Tone knob: Set the cutoff frequency.
Level knob: Set the output level.
Input knob: Set the input level.
Squash knob: Set the threshold for the internal compression circuit.
Contour knob: Set the amount of nonlinear distortion applied to the signal.
Mode buttons: Choose between two fixed high shelving filter frequencies.
Mix knob: Set the ratio between the source and distorted signals.
Fuzz Machine
Fuzz Machine emulates an American “fuzz” distortion effect.

Fuzz knob: Set the input gain.
Tone knob: Increase treble, while simultaneously reducing low frequencies, as you move it to higher values.
Level knob: Set the output level.
Grinder
Grinder is a lo-fi dirty “metal” distortion.

Grind knob: Set the amount of drive applied to the input signal.
Filter knob: Make the sound harsher and more crunchy at higher values.
Full/Scoop buttons: Choose between two fixed Gain/Q filter settings. At the Full position, filtering is less pronounced than at the Scoop position.
Level knob: Set the output level.
Grit
Grit is a hard and nasty filtered distortion effect that sounds great on keyboards and guitars.

Volume knob: Set the amount of drive applied to the input signal.
Filter knob: Make the sound harsher and more crunchy at higher values.
Distortion knob: Set the amount of drive applied to the output signal.
Happy Face Fuzz
Happy Face Fuzz is a softer, full-sounding distortion effect.

Fuzz knob: Set the amount of saturation applied to the input signal.
Volume knob: Set the output level.
Hi-Drive
Hi-Drive is an overdrive effect that can emphasize high frequency content in the signal.

Level knob: Set the output level.
Boost Mode buttons: Set a fixed shelving frequency, allowing either the treble portion or the full range input signal to be processed.
Monster Fuzz
Monster Fuzz is a saturated, slightly harsh distortion.

Roar knob: Set the amount of gain applied to the input signal.
Growl knob: Set the amount of saturation.
Tone knob: Set the overall color of the distortion. Higher values increase treble with a corresponding decrease in overall volume.
Texture knob: Smooth or roughen the distortion.
Grain knob: Set the amount of nonlinear distortion applied to the signal.
Level knob: Set the output level.
Octafuzz
Octafuzz is a fat fuzz effect that can deliver a soft, saturated distortion.

Fuzz knob: Set the amount of gain applied to the input signal.
Level knob: Set the output level.
Tone knob: Set the cutoff frequency of the integrated highpass filter.
Rawk! Distortion
Rawk! Distortion is a metal/hard rock distortion effect.

Crunch knob: Set the amount of saturation applied to the input signal.
Level knob: Set the output level.
Tone knob: Set the tonal color. High values are brighter.
Tube Burner
Tube Burner emulates a vacuum tube-based distortion that provides a wide palette of sounds, ranging from warm grain to crispy overdrive.

Low knob: Set the low frequency gain.
Mid Freq knob: Set the center frequency.
Mid Gain knob: Set the mid frequency level. This affects the range between the Low and High knob values.
Bias knob: Adjust to add or avoid crossover distortion.
Squash knob: Set the threshold for the internal compression circuit.
Fat button: Set at the top position to enhance low frequency content in the signal.
High knob: Set the high frequency gain.
Tone knob: Set the tonal color. High values are harsher.
Drive knob: Set the amount of saturation applied to the signal pre-output.
Output knob: Set the output level.
Vintage Drive
Vintage Drive is an overdrive effect that emulates the distortion produced by a field-effect transistor (FET), commonly used in solid-state amplifiers. When saturated, FETs generate a warmer-sounding distortion than bipolar transistors, such as those emulated by Grinder.

Drive knob: Set the amount of saturation applied to the input signal.
Tone knob: Set the tonal color. High values are harsher.
Level knob: Set the output level.
Fat button: Turn on to enhance low frequency content in the signal.
