There is so much to like about the Barcus-Berry pickup system for bass. First of all, it's called B3150, and how cool is that? It's non-invasive, requires no special installation, is easily transferrable between instruments, mounts effortlessly in many different places on the bridge, and is pretty convenient as far as pickups go, since the supplied cable between the transducer and the preamp is long enough to allow the player to position the preamp out of the way. Now let's talk about what's really important: tone. Acres and acres of voluptuous bass tone, right out of the box, and you can further dial in the sound that works best for you with the treble/bass controls on the preamp and by where you position the transducer. When amplifying a bass, tone is definitely a desirable feature, and the Barcus-Berry B3150 is famous for it. Your Barcus-Berry B3150 pickup system comes feature-packed with the easy-mount transducer, the preamp, a belt clip, a hold-down strap, and some other stuff, along with instructions.
