I have had my solo 610 for probably two years now, and the discontinued solo 110 almost as long. The two have been my go-to preamps in a growing collection that includes Sytek and API, and I still use them all the time. The 610 has a "warm" or "dark" sound that has a lot of "space" or room tone emphasis. It really works well on DI or miked bass guitar, and is usually my first choice for bass in rock sessions. On the other side of things, it's my favorite acoustic guitar preamp. The impedance switch makes it a perfect match for my large collection of high quality dynamic microphones. I find they sound better on the low impedence setting, which is a feature lacking on any of my other preamps. I prefer the 110 for vocals and electric guitar. Hard to go wrong with a UA solo.
Thank you for your feedback on this review. We appreciate your input!
