1. Was your Eden being used to record vocals? If yes, were you using a pop filter? If no, you may have gotten moisture on the capsule. Try letting it "dry" out for 24-hours. If this solves your issue, be sure to use a pop filter moving forward.
2. Is your environment humidity controlled? The Eden capsule is extremely large and thinner than a human hair, which makes it senstive to humidity, moisture and dust. It should be kept at or below 50% humidity at all times.
3. Is the noise always there,regardless? Your Eden likely needs a new tube, which is easy to replace! Click HERE (mailto:sales@lautenaudio.com?subject= New Tube for My Eden)to buy a new one.
