Line 6 Verbzilla Specifications 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 in volume once you stop playing. 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.
