No wonder the RP350 modeling guitar pedal sounds so good. You're looking at the one of the world's most advanced audio processors, the "engine" that gives RP models so much more raw impact and subtle detail. Many manufacturers use general-purpose, off-the-shelf chips. But creating the best guitar tone requires a 100% specialized, optimized processor. Being total audio processing fanatics, DigiTech "Chip Wizard" engineers set out to create a super-processor specifically designed to power a whole new generation of effects and models. The design team worked for over two years, literally re-defining audio signal processing at the chip level. Then "Tone Guru" engineers — fresh from Production Modeling triumphs like the Jimi Hendrix Experience Artist Series pedal — set to work taking advantage of all this new raw processing power. When you hear what AudioDNA2 does for the tone of the DigiTech RP350 you'll agree it was all worth it.*Other product names modeled in this product are trademarks of their respective companies that do not endorse and are not associated or affiliated with DigiTech or Harman International Industries, Inc.
