This hand-held, battery-powered version of the beloved TB-03 is a major home-run from Roland! The new TB-03 has all the features, and familiar layout of the TB-303 with extras added in. In addition to all the beloved tones featured on the predecessor, the TB-03 has a new four digit LED display which makes programming far easier and more accurate than ever before, no more guess-work! There are a ton of delay, overdrive and reverb effects that can drastically change the tone that are included on this updated version. The TB-03 also allows the user to connect directly to your computer via USB and MIDI ports.
