Ear Trumpet Labs Edna is not only visually appealing but also sounds great, providing an accurate, detailed sound with tough and punchy characteristics. The small diaphragm cardioid condenser microphone is housed in a lollipop style capsule made from plumbing flanges and stainless steel bolts. Edna has the clarity along with fast transient responses to be a fine studio mic for acoustic instruments, electric guitars or vocals.
