The Suhr Koko Boost is the ultimate boost pedal in that not only does it provide an extremely transparent clean boost that does not color the guitar's tone whatsoever, but also a selectable midrange boost that works in conjunction with the clean boost to provide you with maximum versatility. Whether you need a little clean boost of your clean sound (up to 20 decibels) or a midrange boost dialed in to overdrive your tube amp for solos that cut through the mix, the Koko Boost is a musical tool that will enhance the sound and functionality of your entire rig with minimum fuss: just plug it in between your guitar and quality tube amp and you are ready to rock.
