Even today, when digital technology allows electronic musical instruments to simulate any sound imaginable, people seek the warm harmonics and distortion produced by analog vacuum tubes. This distinctive sound has a quality beyond words that sets it apart, and cannot be captured by a response curve; it’s the unmistakable sound of tubes. The volca nubass is the first analog synth to be equipped with a Nutube new-generation vacuum tube in its oscillator. Vacuum tube plus analog means that the sound is warm, thick, and rich. The familiar transistor ladder filter gives it the character of a classic bass machine, along with overdrive, and huge-sounding distortion. An acid bass machine for a new generation combines classic sound with the power of modern synthesizer design. It’s the volca nubass.Keyboard: multi touch keyboard + step sequencerAnalog synthesis, monophonicStructure: VTO (vacuum tube oscillator), VCF, VCA, EG, LFO, Overdrive, Tone16 step Sequencer with pattern chain, 16 pattern storageI/O: Audio out/Headphones over 3.5mm stereo mini jackSync out Sync in over two 3.5mm mini jacksMIDI in over 5 pin MIDI din connectorIncluded Items: Six AA alkaline batteries for checking operation, Sync cableDimensions (W x D x H): 193 115 46 mm / 7.61″ x 4.54″ x 1.82″Weight 370 g / 0.82 lbs.
