The Electro Harmonix Dual Expression Pedal allows you to control two suitably equipped effect devices simultaneously, significantly expanding the possibilities for creative expression. Two TRS jacks with switchable polarity ensure broad compatibility, while the reverse buttons and range controls allow the operating range of the pedal to be individually adjusted for each connected one. The Electro Harmonix Expression Pedal can withstand the toughest touring conditions without any problems thanks to the extremely robust yet lightweight housing made of glass-fibre reinforced nylon, which was developed for use in aviation.
