Your Questions Answered About The Korg + Noritake Nutube ‘Vacuum Tube On A Chip’


At the 2015 NAMM Show, Korg and Noritake introduced the Nutube, a new miniaturized, high performance ‘vacuum tube on a chip’.

Korg says that the NuTube generates the musical harmonics of traditional vacuum tubes, but offers three key benefits:

  • Low power Consumption –  less than 2% of the power required by conventional vacuum tubes;
  • Compact – less than 30% of the volume of a conventional vacuum tube; and
  • Reliability – Nutubes offer up to 30,000 hours of continuous operating life.

We asked Korg for more information, based on reader questions to our initial post about the NuTube.

Here are their answers, via Korg Marketing Manager Junko Fukai: Continue reading

Trogotronic Intros High-Powered, Double-Duty, Tube-Based M679 Gran Fury Analog Tube Synth


Trogotronic has introduced the M679 Gran Fury Analog Tube Synth / Bypass Overdrive FX Caveman Module.

Here’s what they have to say about it:

Building upon the legacy of the m676 Fury, the M series 679 Gran Fury has 8 times the patches, 150% more oscillating power, 120% more cv inputs & adds a synth bypass mode to double as a filthy tube distortion unit, all up in your tightly packed rack, it ALL WITHIN the same 14hp as before with zero toll on your already overtaxed power supply.

The sound?

Curiously akin to R. Lee Ermey switching on the kilowatt floods & screaming through an Orange Full-stack set to ’11’ first thing the morning after an all-night gin bender; i.e. relentless punishment applied to all head-holes within audio range.

The Gran Fury’s feature list picks up where the original Fury’s left off: Continue reading

Metasonix R-57 Dual Preamp/VCA Module (Video Demo)

Here’s a video demo of the Metasonix R-57 Dual Preamp/VCA Eurorack module. The new module offers 50db of available gain, assuring ‘true ugliness’.

Metasonix S-2000 Vacuum-Tube Synthesizer ‘A Revolution’


Usually at NAMM time, Metasonix head Eric Barbour is introducing something like the Fucking Fucker, the Assblaster, the Wretch Machine or the Scrotum Smasher.

His latest creation, though, is simply named the Metasonix S-2000 Vacuum Tube Synthesizer. And Barbour calls it “the most exciting instrument in the history of Metasonix”.

Here’s what he has to say about it:

The S-2000 is not merely a new repackaging of old designs. It is a revolution, and a game changer.

The S-2000 was made to be as easy to use as possible. Just plug in power, plug in an amplifier, wait 30 seconds for the real new-old-stock vacuum tubes to warm up, and start playing it. The built-in 400mm ribbon controller is instantly responsive, and needs no special treatment. No trimpots, no fiddling with MIDI interfaces or fighting with fistfuls of cables. The misery has been engineered out.

The simplicity might fool you. The S-2000 has enough controls and enough flexibility to keep the musician busy for years of sonic exploration.

Here’s an unofficial video of the Metasonix S-2000 in action: Continue reading
