Suhr is known for great guitars and..hey the pedal effects! This boost is powerfull and smart,it operates in two ways: clean boost, crystal clear ,gorgerous; mid boost, here comes the fun..mid Q and mid boost are the knobs that will change your sound and push it to the limits of your imagination. The good news is another one! it has a toggle switch that puts the KoKo in three different regions of your sound: mid ,low mid,high mid. Now you can spend the rest of your life trying to understand how many things can change with a simple boost. To me, together with Tc Electronics sparkle, is the best boost on the market.
