Buying one Quad4 is like buying 4 independent processors. Inside the Quad4 is a multi-effects processor that is multi- talented, and while most of us can't do more than one thing at a time, the Quad4 can do 4. Why did we put the power of 4 multi-effects processors into one unit? So you, too, would be able to do more than one thing at a time. The Quad4 features 4 completely independent inputs and outputs that give you the power of four independent mono processors or two true stereo processors. Imagine the power to process two true stereo sources simultaneously without sacrificing control.

But true stereo is only the beginning. Imagine having 4 independent reverbs for vocals, guitar, keyboards, and drums, where each reverb can be optimized specifically to achieve the best audio performance for each application. And imagine a processor that gives you the power to create any combination of effects, in any order. And then multiply by four. Check out the Quad4. With its ingenious user interface, large custom display, and potent S-DISC II® technology at its heart, the Quad4 is capable of not just replacing, but thoroughly eliminating the need for multiple, expensive, single-purpose processing units. You work hard for your money. DigiTech makes sure you get the most for it.
