Critic Reviews

DigiTech Dirty Robot review | MusicRadar

musicradar.com

For adventurous guitarists, the DigiTech Dirty Robot is a gateway to synth-like soundscapes. With faultless tracking and robust construction, it offers two synth voicings: an envelope-style synthesis and a vocal formant mode reminiscent of classic 80s sci-fi. While it excels in capturing fast runs and adding flair with onboard filters, its niche appeal means it's best suited for those looking to blend synth effects into their music. Overall, it's a unique pedal that delivers on its promise of transforming guitar tones, making it a worthy addition to any experimental setup.

Fun and Robotic

I finally got this pedal right at the pandemic while working on a soundtrack and have used it several times when the funk needed an odd bite. This pedal is similar in ways to the BitCommander in that you can color the sound yet the bass remains solid!

This thing is CRAZY!

I still have to find the right definition for this little fella... It gives you AMAZING possibilities and unique sounds. It's not for everyone and surely it is for people that love experimenting new ways to subtly deform your sound or to completely morph it into a broken robot talking wah! I used it in 2 ways:

Hidden boost behind my "The Dude" overdrive, to add a unique rounded dirty boost
By it self with a compressor as main protagonist of my sound... it sounded FAT!
