I've had this thing for several years now, and I got it used. It may be designed with Baggs pickups in mind, but it sounds great with other brands as well. I use it on guitar and mandolin. Left at unity, it sounds fine, but a four-band eq with sweepable mid, plus notch and phase invert will allow you to dial in the sound you need in any room. Mine has seen heavy use, and is still going strong -- it's built like a tank. It would be nice if it were less expensive, but you won't need to replace it.
