The Electro-Harmonix Mod11 Modulator Machine is a mash-up of 11 modulation effects crammed into one stompbox. With a range of classic and exotic effects to choose from, you can take total control over your guitar's sound and create truly one-of-a-kind tones. You can use the depth, rate, and color knobs to dial in your tone easily. Guitarists at Sweetwater especially liked the "hidden" parameters that you can access with the mode control. The Mod 11 comes equipped with momentary mode to add quick flashes of modulation and tap tempo. The tap tempo feature can be used with the onboard footswitch or an external switch. The Electro-Harmonix Mod11 will be the Swiss army knife of modulation for your pedalboard.
