Description
The Suhr Koko Boost earns its spot on countless pedalboards for one simple reason: it gets out of the way. Set it for pure clean boost and it adds up to 20dB of gain without smearing your guitar’s natural voice — no added coloration, no lost dynamics. Flip on the midrange boost and you’ve got a second tool entirely, one that shapes the frequencies your tube amp needs to break into a singing, cutting overdrive for leads and solos. Run both together and you dial in a level of push and tone-shaping that most single-function boosts can’t touch.
Placement is straightforward: guitar in, quality tube amp out. Whether it lives at the front of your chain for an always-on gain nudge or gets stomped on for solo sections, the Koko Boost adapts to how you actually play rather than forcing you into one use case.
