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.

Pitch Glide is most effective when used with an FBV™ MkII foot controller. Use the foot 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, 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.

Simultaneous FX

Use up to 8 effects at the same time! Pour on the colors and textures with all 4 Smart FX, set the Boost and the Noise Gate, activate Quick Loop, and connect an FBV MkII foot controller to kick on the volume/wah pedal. How many other amplifiers can deliver that?

Manual Mode.

Manual mode draws a more traditional amplifier experience out of Spider IV. When Manual mode is activated, all front-panel knobs work independently of one another. Out of Manual mode, choosing an amp model may adjust the settings of the other front-panel knobs.

Stay focused

To get the whole story of Spider IV amplifiers, you need to turn one around. All Spider IV combo amps feature a perfectly tuned three-quarter closed-back cabinet. This provides a tight, punchy, focused response that you can’t get from an open-back cabinet.

A large, two-line LCD is your window into Spider IV. This is where you can deep dive into effects and adjust their parameters, scroll over 500 presets, see the tuner interface, name your user-created presets, get a visual representation of where your Smart FX knobs are set, and more.

Downloads and upgrades

Keep your Spider IV up to date! We frequently release firmware updates for our gear, and they may include new features, presets, or effects. To check for updates, all you have to do is connect your Spider IV to an FBV MkII foot controller, and connect the FBV MkII foot controller to your computer. Run Line 6 Monkey™ and off you go!
