Pitch effects.

Smart Harmony is our first intelligent pitch shifter. It's fast-tracking and easy to use. Harmonize using major, minor, pentatonic, whole tone, and other types of scales. (Don't worry, you don't need to know music theory to use Smart Harmony).

To get the most out of Pitch Glide, connect an FBV™ MkII foot controller. Use the foot controller's pedal to smoothly shift your tone up or down to any interval within a four-octave range. Calibrate the effect to semitones, or to 10-cent increments to create cool chorus/detuning effects.

Quick loop.

Quick Loop is a 14-second sound-on-sound looper that's ideal for writing songs, practicing solos, overdubbing, jamming, and even dialing in your tone! Easy to use, Quick Loop's controls are all on the front panel. Connect an FBV MkII foot controller for hands-free control of the looper functions.

System FX.

Put the finishing touches on your tone with new System FX. Noise Gate helps you eliminate hiss from noisy pickups, and white noise from extremely high-gain distortions. Boost punches up the volume of your solos to make them really pop. (Up to +8 dB pre, post or both.) Volume routing pre or post gives you unparalleled control over your sound.

Window to the soul.

A large, two-line LCD is your window into Spider Valve MkII. This is where you can deep dive into effects and edit their parameters, scroll your user presets, see the tuner interface, get a visual representation of your Smart FX settings, and more.
