With the 200 series, BOSS introduces a new generation of pedals that pack advanced sound and versatility into a streamlined size that saves space on your board. Grab-and-go controls and multi-function switches make operation easy and intuitive, while onboard memories allow you to store multiple setups for instant recall. All 200 series pedals feature premium audio quality with 32-bit AD/DA, 32-bit internal processing, and 96 kHz sampling rate, as well as support for additional control via external switches, an expression pedal, or MIDI.

The EQ-200 is the most flexible compact EQ ever created for guitar and bass. It features two wide-ranging 10-band EQ channels, plus an onboard graphic display that shows the current EQ curve at a glance. Selectable signal flow structures configure the channels for stereo, parallel, or series operation, and it’s even possible to patch in external pedals for deep pre/post tone shaping. Going further, the frequency centers of all 10 bands can be set to three different types, letting you optimize the EQ-200’s performance for different instruments.

Version 1.1 Update: User Memory Expansion

The free Version 1.1 software update brings increased flexibility to the BOSS 200 series, greatly expanding the onboard memory capacity for storing and recalling sounds. There are now 128 user setups available. Setups can also be recalled directly via MIDI program change.

The Version 1.1 update is available in the Downloads section for each 200 series pedal.
