Aside from their powerful and responsive output, one of the first things you'll notice about Roland's D-Bass Amplifiers is their relatively compact size. The small-yet-powerful design of the D-Bass amps is thanks to Roland's proprietary Feed Forward Processing (FFP) technology, which digitally controls the output of these amps to sound much cleaner, louder and punchier than their conservative wattage ratings would suggest.

Digital Amps with an Analog Soul

Thanks to breakthrough COSM amp modeling technology, the D-Bass Amplifiers can deliver a range of great tones beyond that of a traditional (analog) bass amp. Simply select from "Solid State," "Tube" and "Tube Drive" models and use the simple, knob-based controls to tweak your sound as you desire. Once you've got the tones you like, save them into memory for instant recall.

A Range of Sounds and Colors

The D-Bass amps don't stop with amp modeling. They also incorporate specially tuned compression—both clean and overdriven—that you can adjust and save into memory; a 3-band EQ with a semi-parametric midrange; and a Shape switch for tightened response when slapping or popping. There's also a specially tuned "D-Chorus" effect which adds lush, dynamics-sensitive chorus to the high-end without muddying up the punchy lows.

Easy-to-use Controls

Though they incorporate very sophisticated processing inside, the D-Bass amps are refreshingly easy to use. Straightforward knobs give you control over Gain, Volume, Compression, Bass, Mid, Mid Freq., Treble, Chorus and Master Volume. Once you've got the tones you're after, simply save them into A and B memories for instant recall via buttons or optional footswitch. Other conveniences include a high-quality DI output (XLR type), plus a 1/4-inch output for recording. There's also a Headphone jack and a dedicated Insert jack for connecting to external effects.
