A customer came in a few days ago and asked what one of my recent favorite eurorack modules was. I fired up the Trogotronic 679. His mouth was open in disbelief. It was a look that said “you are insane”. Well maybe I am. Ultra Twin -Triode Vacuum Tube distortion that for the weak and scared does sound insane. This video shows the simplest use of the 679 tube synth-as a distortion unit for an audio signal. The videos using the 3 oscillators and other modulation features is coming soon. A yet to be announced standalone table top version of the Gran Fury 679 will arrive next week. robotspeak/collections/trogotronic/products/679 Product Description 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— 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. Gran Fury’s feature list picks up where the renown Fury’s left off: ▪ All Analog Circuit ▪ Audio Input for synth Modulation ▪ Oscillator Bypass Setting for use as Tube Distortion FX ▪ 3 Main-Oscillators with Vactrol CV inputs ▪ 4 Amplifier Stages: 2 Solid State + 2 High Voltage Tube ▪ 2 Unique Vactrol CV FX parameters (Drive & Modulation) ▪ 1 Master Frequency Control of Oscillators: Track ▪ 6 CV Input Attenuators ▪ m679′s 5 Toggles = 8x More Internal Patch Combinations than Original m676 ▪ Amplifier Boost / Synth-Bypass Switch ▪ Compatible w/ Alternate Tubes for Auxiliary Plug & Play Sonic Profiles ▪ Uses Includes Dedicated High Current Power Supply ▪ Uses ZERO mA of Your Rack’s Existing Power Supply ▪ Slovakian Max. Gain, Twin-Triode Vacuum Tube run at High Voltage Yes: “high voltage”—no small task for a euro module. Reason being: even the best euro format power supplies were never intended for providing “B+” (arcane engineer speak denoting High Voltage feed for vacuum tubes). Rather than compromise both the operating specs of the tube & capacity of your modular’s power supply the M Series 676 ships with it’s own. Simply plug in the included wall-wart, give the tube a few seconds to warm up & voila! Tangled in wires already? We get it: in addition to the power jack on the face there’s another power tap hidden on the rear of the module should you want to get crafty to keep things clean. The advantage is twofold: no capacity is taken from your existing supply and the vacuum tube employed is a common model in current production (so there is no worry should it require replacement after many years of faithful service). Further a whole host of current production twin triode tubes (we sell three types here) are plug & play compatible, each giving the Gran Fury a subtle sound profile of its own. Like any Trogotronic worth its salt the 679 Gran Fury’s functions are not conservative; While there are 3 Oscillators, other parts of the circuit can command more complicated frequencies in an intuitive manner. Similarly the Oscillators themselves may be applied as filters / modulators serving to broaden the utility of the instrument even more so. Add to this the inclusion of 6 CV inputs compatible with sequencers, envelopes etc. plus distortion mode & suddenly your vanilla rack is moonlighting as a cruel mistress at that deviant dungeon downtown wearing earplugs so as never to hear the whimpered safe word: “Gran Fury!”
