BOSS EQ-200 is possibly the most versatile graphic equalizer pedal ever devised for guitar and bass. And thanks to its stereo I/O, it could be a big benefit to your keyboard rig too. The EQ-200 actually offers dual EQs that can be configured for stereo, series, or parallel operation, and an insert function even allows you to add external effects pedals with pre- and/or post-equalization. Each band offers 15dB of boost or cut, and thanks to its global level control, you can even tailor the BOSS EQ-200 graphic EQ pedal to be your go-to boost pedal as well.
