Designed for the real-world needs of professional performing musicians, the ES-8 from BOSS is a highly programmable guitar effects switching system offering an unprecedented amount of routing flexibility. The ES-8 features eight effects loops with the ability to change the routing order and create parallel effects chains. The loops are controlled by an analog switch array that provides fast, flexible, and transparent switching. When a loop is not active, your guitar completely bypasses it for clear and pure signal transfer. Separate input and output buffers are available, and these can be switched on/off individually as needed.

The ES-8 features inputs for two guitars and outputs for two amplifiers, as well as send and return for six mono effects and 2 stereo effects. Additionally, there are several external control inputs for foot controls and expression pedals, as well as full MIDI compatibility. The bright display offers an easy-to-read layout well suited for dark stages. The 800 presets offer ample room for storing patches for the ultimate flexibility while touring and performing. The ES-8 ships with an AC power adapter, two pedal board mounting screws, and five rubber feet for standalone use.
