The TB-03 Boutique Bass Line from Roland brings the legendary TB-303 Bass Line synthesizer into the modern age. With authentic circuitry modeling the original's unmistakable sound and hands-on controls, the TB-03 lets you craft searing acid basslines and twisted lead tones with vintage vibe. But it also packs new creative tools and mobile-friendly features that make this compact groove box an ideal addition to any studio or stage rig.

The Iconic TB-303 Tone and Interface

From the moment you lay hands on the TB-03, it feels like you're playing a vintage TB-303. All the original's expressive rotary knobs are there, including tuning, cutoff, resonance, envelope mod, decay and accent. Twisting these lets you precisely shape the signature acidic tone that made the TB-303 a club and studio staple. Both saw and square waveforms are on tap, allowing for everything from squelchy basslines to piercing lead melodies. It's the most authentic way to experience the magic of this cult classic outside of owning an original unit.

Powerful New Creative Features

While it stays true to the vintage vibe, the TB-03 expands on the original's capabilities in some very useful ways. A bright, four-digit LED display provides visual feedback that makes programming patterns faster and more precise. Newly added overdrive and delay effects let you get wildly aggressive or add spacious atmosphere to your patterns. New writing functions like Step mode, shuffle and fine tempo control unlock fresh creative possibilities. And you can now seamlessly transition between writing and playback without stopping the sequence.

Integrated With Your Modern Music Rig

Despite its vintage soul, the TB-03 is very much a modern instrument made for integrating with current music production setups. It features MIDI In/Out for syncing with other MIDI gear, as well as a USB port for connecting to your DAW as a 24-bit/96kHz audio interface. There are even CV/Gate outputs for controlling vintage analog synths and modern Eurorack modulars. A dedicated trigger input allows external gear to drive the TB-03's internal sequencer. This level of connectivity makes the TB-03 a supremely versatile addition to any electronic music studio or live rig.

Built for Mobile Music Making

Part of the appeal of Roland's Boutique line is their compact size and portable power options that make them ideal for mobile music creation. The TB-03 runs on four AA batteries or USB power, allowing you to craft new ideas whenever inspiration strikes, without being tied to a power outlet. Its solid build quality with a metal front panel ensures it can withstand the rigors of the road. Additionally, the included custom Decksaver cover protects those legendary knobs and switches from harm when it's time to pack up and move to the next spot.
