Description
The Koko Boost earns its spot on countless boards for one reason: it disappears into your rig until you need it. Suhr built this as two tools in one enclosure — a clean boost that adds up to 20dB of level without smearing your guitar’s natural voice, and a separate, selectable midrange boost that shapes and pushes your signal for solos that punch through a dense mix. Run them independently or stack them together for a fully custom gain profile.
Placement is simple: drop it between guitar and a quality tube amp and let the amp do the heavy lifting. The clean boost side stays true to your instrument’s character, so it works equally well for a subtle volume nudge or slamming the front end of your amp into natural saturation. The midrange boost is voiced to cut, making it a go-to for lead lines that need to stand out live.
