Congratulations on your purchase of the Barcus-Berry Strings System
for 3125 (Cello) or B3150 (Upright Bass)

Barcus Berry string instrument transducers have long been the preferred choice of leading professionals throughout the world.
The Model 3125 for cello and B3150 for upright bass continue this tradition of excellence by incorporating some of the most
advanced transducer design technology available. These transducers can be quickly and easily attached to or removed from any
standard-type bridge. They have wideband frequency response, essentially unlimited dynamic range and excellent string bal­ance. In addition, they offer a high degree of feedback rejection and outstanding signal isolation. These characteristics, coupled
with unexcelled reliability, make the 3125 and B3150 ideal for virtually all sound reinforcement and studio applications. These
transducers can be employed with all types of instrument setup; plain or wrapped gut, nylon-core or steel-core strings can all be
used in any desired combination.
