KATANA SOUND is a high-end effects pedal brand, each one handmade. There are many boosters on the market that are simple, compact, and lift the sound without altering the original tone, but the One Booster not only boosts the sound, but also makes the sound's contours stand out clearly, and is an outstanding pedal with low noise. If you want to add a little something to a dull sound, it's also good to leave it on as a buffer from the start of sound making, rather than as a booster. Used item in excellent condition with almost no scratches. Highly recommended. This is a rare, discontinued item! Get yours quickly! KATANASOUND ONE Booster Effects Pedal.
