Bass amp technology takes a big stride forward.

Roland's most advanced bass amplifier employs proprietary Feed Forward Processing (FFP) with Active Speaker Control technology for a marked increase in speaker efficiency and response, loudness, and tone.

COSM Vintage, Modern, and Super Flat preamps deliver a range of great tones beyond that of a traditional bass amp with simple, analog-style controls. The Super Flat setting reproduces the sonic characteristics of your bass without coloration and its fat and clear sound is perfect for bridge and soundboard pickups on upright basses. Solid state or fat, natural, Tube Logic compression smoothes out your attack for rich, pro-level tone.

The front panel has normal and piezo-level inputs, active/passive switch, gain, preamp type knob with Shape switch, 4-band semi-parametric EQ, a tweeter control knob, effect blend, master volume, mute switch, and headphone jack. On the rear is a footswitch jack, effects loop I/O, subwoofer out, line out, tuner out, and the XLR D.I.

An optional powered extension speaker adds another layer of punch for performers who play larger venues. (See accessory box on this page.)
