DigiTech RP Multi-Effect Pedals
SIDEBAR: Genetic Engineering
At the heart of the new RP series is the proprietary AudioDNA2 digital signal processor, four times as powerful as the previous AudioDNA processor. The AudioDNA2 is a proprietary chip cooked up exclusively by Digitech and designed specifically for audio processing. I spoke at length with Digitech's David Rohrer about the benefits of the AudioDNA2 chip. "It's important to understand that this is not an offthe- shelf chip, like something you'd find in a telephone or a car dashboard. The AudioDNA2 chip was designed only for audio processing," notes Rohrer. "Furthermore, it provides even greater accuracy, authenticity, and dynamics than the earlier AudioDNA processor. You'll hear it in subtleties of dynamic response, in direct comparison of our amp models to their vintage counterparts, and in things like how an amp model cleans up when you drop your guitar's volume."
Did any of the other Digitech lines influence the upgrades in the RP modeling processors? "Absolutely. We learned a lot when we developed the Artist Pedals, for example. Working with talents like Brian May [for the Red Special pedal] and [engineer] Eddie Kramer for the Jimi Hendrix Experience pedal gave us some deep insight into capturing the essence of great tone. That kind of focus on tonal sculpting went into these new RP pedals. And it's not just the guitar-processing tones that reap the rewards of AudioDNA2. It's been used to enhance the drum samples used in the RP's built in drum machine as well," says Rohrer.
