It used to be said about mando pickups that your mando could either be heard, or it could sound natural. The Baggs pickup is the best of both worlds. It is strong without distorting - even without a preamp. I can be heard in the band above a fairly loud electric guitar. It also sounds very natural and warm, picking up a good mixture of tone and percussiveness.
The sticky mount is very dependable. The side clamp mount, however, takes a little care to make sure it doesn't slip off. When you pick up the mando when it is plugged in, you need to grab the patch cord as well so it doesn't get caught and pull off, and you need to push against the plug-in base with your thumb when you unplug. Once you get in the habit of doing this, it's no big deal, especially when weighed against the good sound quality of this pickup.
