The L.R. Baggs iBEAM Active Acoustic Guitar Pickup System combines the iBeam transducer pickup with an all-discrete, Class A FET preamp built on a stereo Strapjack and pre-tuned to deliver plug-and-play L.R. Baggs performance. The preamp also features a second active input, so you can easily run a second pickup to complement the L.R. Baggs iBeam.
