This is a Tubetech tube microphone preamplifier, a classic piece of equipment often seen in recording studios. It's a valuable tube mic pre that's become rare these days. The sound quality is what you'd expect from professional-grade equipment. It has a richer expressiveness and a better response than NEVE-style preamps, in my opinion. Rather than the warmth typically associated with tubes, it offers a clear and large sound image. It will be shipped in its original box (which is old, so consider it as packaging material). As a bonus, I can include replacement vacuum tubes (from various manufacturers) if you'd like.
