Critic Reviews

Electro-Harmonix Stereo Talking Machine Pedal Review - Premier Guitar

premierguitar.com

The Electro-Harmonix Stereo Talking Machine impresses with its ability to create iconic talk-box tones and more. Its modern features like preset management and digital conversion are commendable, along with a fuzz circuit and extensive control options. The pedal's ability to replicate vowel sounds and provide expressive formant filters is noteworthy. However, the multitude of knobs and multi-function controls might be overwhelming for some users. If you're after versatile vowel sounds without the cumbersome tube, this pedal is a great pick. But if complex controls deter you, it might not be the best fit.

EHX Stereo Talking Machine Guitar Effects Pedal Review

gear-vault.com

The Electro-Harmonix Stereo Talking Machine is a versatile vocal formant filter pedal that delivers an impressive range of sounds from wah and talkbox effects to envelope filters. Its programmable nature allows for easy storage of up to 18 presets, offering flexibility for both stage and studio. While the pedal's complexity might be daunting initially, its auxiliary mode unlocks additional tonal possibilities, including legendary EHX fuzz. However, the lack of an included expression pedal might require additional investment. Overall, the Stereo Talking Machine stands out as an innovative tool for musicians seeking to add expressive, speech-like tones to their sound palette.

I love pedals, period. I have over 100 in total, I think; there’s stuff that I probably don’t even know I own (laughs). My favorite is right now is the Eventide H9, it’s so diverse and the quality of the effects is amazing. I also really like the Electro-Harmonix Talking Machine. And I’ll usually collect anything that Jack White uses, all his limited edition stuff like the Gamechanger Audio Plasma Coil.
