Line 6 ToneCore Verbzilla Guitar Effects Module Features:

Model Switch - This switch is used to select from 11 distinctly different types:
'63 Spring - Based on* a Fender© 1963 brown spring reverb head unit. Best known for great surf guitar tone!
Spring - Based on a studio spring reverb.
Plate - Based on a studio plate reverb.
Room - Simulates the acoustic properties of a classic echo chamber that consists mainly of early reflections.
Chamber - An elongated ambient space such as a hall, stairwell or elevator shaft creates this reverb type. Dreamy.
Hall - Simulates the sound of a concert hall or large open space with a strong reverb tail. Imagine a gymnasium, performance hall, or cathedral.
Ducking - Built using a 'Hall' but with a ducking effect. The volume of your reverb is "ducked" (reduced) while you're playing, and increases when you stop. This allows for clean musical passages with a touch of reverb that ramps up
Octo - Creates a lush, ambient space with a harmonized decay whose harmonic denseness is controlled by the time knob. Use volume swells and prepare to float on a cloud!
Cave - Surreal cavernous echo chamber.
Tile - Emulates the acoustic reflections of a tiled room, such as a bathroom with bright early reflections.
Echo - Just like it says ...echo...echo...echo.
Mix - Allows you to control the amount of reverb in your signal from dry to 100% wet.
Decay - Controls how quickly the reverb tail fades to silence.
Time - Controls the length of pre-delay. This is the amount of delay before the signal hits the reverb chamber.
Tone - Allows you to adjust the tonal character of the reverb, giving you the flexibility to go from dark and subtle to bright and splashy.
Trails Switch - When switched on, Verbzilla's processing is engaged while in bypass, so reverb smoothly trails away when you kick the effect off.
