Capturing the inimitable tone of a gear legend and making it accessible to the modern musician, the Roland TB-03 Bass Line Synthesizer is an attractive piece of equipment for any synth enthusiast. Borrowing the Analog Circuit Behavior (ACB) technology that put the AIRA series on the map, the TB-03 serves up that same tribal, undulating bass sound as the original but in a chassis that you can fit in your bag. Speaking of the chassis, you'll find that this update retains the feel and workflow of the original with updates like a four-digit LED display, coveted TV sequencing with write and playback modes, and USB/MIDI connectivity for making sure this low-end monster plays nice with your other gear.
