Stored in a dehumidified cabinet until sold. This is a handmade item by Kagaboo. [Product Description] This is a FET condenser microphone created with the aim of reproducing the acoustic characteristics of the legendary vacuum tube microphone, the U67. It was created using a 34mm diaphragm K67 type capsule (obtained on eBay). The characteristics of the vacuum tube EF86 were analyzed, and the features were reproduced using a FET circuit without using a vacuum tube. All components use audiophile-grade materials, including ELNA and Nichicon capacitors and audio transistors. The output transformer is not a pre-made product, but an original custom-made for this microphone. It produces a silky sound that recreates a vintage feel. Suitable for voiceovers, vocals, and recording a wide range of instruments. It has low self-noise and is a microphone that both professionals and amateurs will be satisfied with.

This microphone is unidirectional. This product operates only with phantom power (48V). I am reluctantly selling this to raise funds. I believe it is a very good microphone. Type...Microphone
