FFP upgraded with Active Speaker Control
To achieve their high-quality sound and amazing performance, the new D-Bass amps employ breakthrough Roland technology: FFP incorporating Active Speaker Control. FFP (Feed Forward Processing) is a DSP-based process that analyzes incoming signal and maximizes it before it hits the speaker. By utilizing Active Speaker Control, FFP allows the D-BASS to faithfully reproduce the incoming signal of the original bass, thereby controlling its speaker movement to reproduce the same input signal as closely as possible. This "true input matching" technology allows lower-string sounds to be much clearer, and the overall feel to be more direct than with other bass amplifiers.… read more A technology exclusive to Roland amps, FFP provides a marked increase in speaker efficiency, loudness boost, and overall perceived power.

Road tough, lightweight
Don't let their lighter-than-average weight fool you. These amps are tough as nails and built for the road. Equipped with high-performance, low-weight neodymium speaker magnets, each new D-Bass amp is a performance powerhouse that's a joy to transport. Industrial strength, smooth-rolling casters make the job of getting from gig A to B even easier.

COSM preamps
Equipped with Vintage, Modern, and Super Flat COSM preamp models, the D-Bass 115's COSM preamps can deliver a range of great tones beyond that of a traditional analog bass amp. With the simple, analog-style controls, you can control your sound quickly and easily. Roland's unique "Super Flat" setting reproduces the bass guitar's original sound characteristic without coloration. Its fat and clear characteristic is also perfect for the piezo sound of upright bass. Detailed sound adjustments are possible with the 4-band EQ, including a dedicated tweeter control knob.

Two compression types
The 115 D-Bass amp is equipped with pro-quality solid-state compression, plus a Tube Logic section. Derived from Roland's BluesCUBE, the newly improved Tube Logic produces the type of fat and natural compression associated with vintage tube amps. No matter how razor-sharp the tone, Tube Logic can dunk it in a liquid-warm bath.

Satellite power
Need more beef? Add a D-Bass 115X powered speaker cab. Designed to be a perfect match electronically and physically for the D-Bass 115, the 115X provides 300 crushing watts of add-on power for the extra volume and punch required by larger venues and stages. The 115X has a switch for full range or sub woofer mode, affording players the flexibility they need to maximize their rigs from stage to stage. read less
