Reverb type Description
Vintage Spring This bright, splashy sound has largely defined combo amp reverb since
the early 1960s.
Simple Spring A darker, subtler spring sound.
Mellow Spring An even darker, low-fidelity spring sound.
Bright Spring Has some of the brilliance of Vintage Spring, but with less surf-style
splash.
Dark Spring A moody-sounding spring. More restrained than Mellow Spring.
Resonant Spring Another 1960s-style spring with a strong, slightly distorted midrange
emphasis.
Boutique Spring A modernized version of the classic Vintage Spring with a richer tone in
the bass and mids.
Sweet Reverb A smooth modern reverb with rich lows and restrained highs.
Rich Reverb A rich and balanced modern reverb.
Warm Reverb A lush modern reverb with rich lows/mids and understated highs.
Logic Pro Amp Designer tremolo and vibrato
Tremolo and vibrato are controlled by several switches and two knobs in the effects
section. Tremolo modulates the amplitude or volume of the sound, and Vibrato modulates
the pitch of the sound.
Tremolo and vibrato parameters
• On/Off switch: Turn the tremolo or vibrato effect on or off.
• Trem/Vib switch: Choose either tremolo or vibrato.
• Depth knob: Set the intensity of the modulation for either tremolo or vibrato.
• Speed knob: Set the speed of the modulation in hertz. Lower settings produce a smooth,
floating sound. Higher settings produce a rotor-like effect.
• Sync/Free switch: Choose Sync to synchronize the modulation speed with the host
tempo. Choose free to set values with the Speed knob. In Free mode, you can use the
Speed knob to set the modulation speed to different bar, beat, and musical note values
(1/8, 1/16, and so on, including triplet and dotted-note values).
