Critic Reviews

Electro-Harmonix Clone Theory review | MusicRadar

musicradar.com

The Electro-Harmonix Clone Theory offers a workable chorus effect with added vibrato mode, but it doesn't quite deliver the sonic punch expected from an E-H pedal. While its vibrato mode adds unique character, the pedal's overall sound is somewhat underwhelming compared to its peers, like the Small Clone. The lack of convenient battery access is a downside, and there's noticeable hiss that could be a dealbreaker for some. However, its sturdy build and stereo capabilities provide versatility, making it a decent choice if you value these features over pristine sound quality. Give it a thorough test at high volume to ensure it meets your needs.

"Then there were loads of smaller pedals - a Colorsound Toneblender, an Electro-Harmonix Big Muff, a Daddy-O, a Rat fuzz, plus an old Electro-Harmonix Clone Theory which is excellent for a really shitty chorus sound."
