【Universal Audio SOLO/610 Tube Preamp】 This is a popular Universal Audio tube microphone preamp and DI, bringing vintage Neve-style sound to the modern era. With its thick and warm sound derived from the 610 console, it's ideal for a wide range of sources, including vocals, guitars, and bass. 【Condition】 Operation confirmed. During operation check, noise was present when the gain was set to 5 or higher. While you may not need to raise the gain that high, please keep this in mind. The control knobs and switches on the front panel are in good condition. The microphone input, output, and various switches on the back panel are in good condition. The exterior has some scratches, especially on the bottom. I have used it with care in my home recording environment. I am an amateur, but I will answer questions as best I can, so please feel free to ask. I can also provide additional photos, but please understand that I cannot inspect the circuit board, etc., as I am not a professional. 【Accessories】 Main unit, power cable, original box, instruction manual. 【Other】 Recommended for those who want to add the thickness and warmth of analog sound. It has an overwhelming presence, especially for vocals and bass DI.
