Critic Reviews

Electro-Harmonix Cntl Knob review | Guitar World

guitarworld.com

The Electro-Harmonix Cntl Knob is a compact and budget-friendly alternative to traditional expression pedals, designed to save space on your pedalboard while providing effective control over effects. It allows users to toggle between two user-defined expression values, making it a versatile choice for various applications. While it lacks the tactile feedback of a treadle pedal, this trade-off is minimal considering its affordability and functionality. The only drawback noted is the absence of a treadle for those who prefer physical control, but for many players, the compact design and ease of use far outweigh this limitation. Overall, the Cntl Knob expands pedalboard possibilities without breaking the bank.
