Super underrated preamp. One of those well-kept secrets. Very careful use since I bought it - mostly in the studio. It does a great job of adding body to small or thin-sounding acoustics, especially with passive pickups. Awesome gain circuit for tasteful saturation. Great set of I/O, including a dedicated FX loop and tuner out. Everything you need, with some extra special sauce, for a really good price. Power supply in excellent condition.
