  •     The ES-8 scratches all the itchy points of today's discriminating artists which no other switching system has yet been able to reach.
  •     Programmable switching system with eight loops (plus an additional loop)
  •     Analog circuit design to protect your pure tone
  •     Unprecedented routing flexibility with the ability to change the routing order and create parallel effect chains
  •     Onboard memory for storing external control parameters such as delay time for each patch
  •     Buffers can be turned on/off individually each for input and output and stored in each patch; level variability for output buffer
  •     Highly-reliable footswitches with switch-noise mute capability
  •     LCD and 7-segment LED display show detailed information at a glance
  •     800 patch memories provide unmatched capability for touring musicians
  •     Completely customizable pedal function assignments
  •     Scratching the itch of serious working musicians with detailed attention to often-requested features and functions



    One of the ES-8’s key features is its innovative routing flexibility, which provides the ability to easily rearrange the order of a chain of stompbox effects. This gives professional guitarists the ability to access a wide array of effect combinations, offering total creative freedom to achieve the unique sounds that they desire. In addition, the ES-8’s parallel chain function increases the effect combination options further, thereby expanding the final sound variation capability exponentially. What’s more, all of these programmed configurations can be saved for instant access during a live performance.


    Supporting the ES-8’s superior functionality is its comprehensive connectivity, which empowers this amazing switcher to do the job it does. In addition to the eight effect loops on board, there are three TRS control output jacks, two TRS expression output jacks, and two TRS control/expression input jacks. MIDI capability is also included for integrating seamlessly with MIDI-controlled stomp effects. These centralized controls make the ES-8 even more powerful as a total command center of sound creativity. Of course, as is consistent throughout the ES-8 system, all of these control settings are also storable.


    In addition to routing capability and connectivity, the ES-8 pays particular attention to sound quality. It’s designed in a way that does not contribute to sound deterioration, keeping your tone pure and free of noise. These results are accomplished by carefully designed analog circuitry developed with the know-how, experience, and design expertise of the Boss engineering team. In further regard to tone pureness, the ES-8 is equipped with input and output buffers that can be turned on and off independently as needed to suit any rig.


    The ES-8 effect switching system is more than just a smartly designed tool for the creation of awesome sounds. It is also a handsome piece of hardware that is going to look really good on your pedalboard. Built with durable mechanical functions in a road-tough design, the ES-8 combines huge technical innovations with small useful conveniences. Memory capability with 800 patches, a large display with extensive naming capacity, and robust responsive foot switches with full assignability are just a few of the features that make this switcher the choice of the pros.
