Bass amp technology takes a big stride forward with the new D-Bass series. Roland’s newest and most advanced bass amplifiers employ proprietary FFP™ with Active Speaker Control technology for lightning-fast response and ultra high-quality bass tone. Two combo-type models (210 and 115) offer different wattages and speaker configurations to accommodate a variety of needs and tastes. A powered extension speaker (model 115X) adds another layer of punch for performers who play larger venues.
