"What an absolute pleasure to have Finlay of Future Sound Systems and Roy Gwinn present the new Gristleizer modules at Modular Meets Leeds 2017. Unfortunately Chris Carter couldn't be with us on the Sunday (although links to his performance and interview below) but Roy shared his stories of the original unit created when he was only 15 years old, revisions, ideas, googling his own name and Finlay then took us through a series of killer audio demos with Mutable Instruments Braids through the modules, electric guitar and beats from a Korg Volca. I feel honoured to have people like this involved with Modular Meets so thanks to all involved! "

"Here's a great noisy and experimental #3modulechallenge from Finlay at Future Sound Systems. He's using the FSS Pin Matrix as well as two of the new Gristleizer modules from FSS in collaboration with Chris Carter and Roy Gwinn."
"This is #6 of the original run of Gristleizers made by Endangered Audio in Asheville, NC. These are the only Gristleizers officially endorsed by Chris Carter and Throbbing Gristle. This was my personal Gristleizer from 2009 until now. TG got serial numbers 1-5, I got #6, and the owner of Endangered Audio Research got #7. Serial numbers 8-15 were sold at the Logan Square show in Chicago during TG's reunion tour of the USA. This effect is a big part of TGs sound as well as their history. I personally presented TG with their Gristleizers in Chicago. There are photos documenting the occasion on Chris Carter's website gristleizer.com.
This until shows some signs of use and the CV in and out mod was done at some point. There is an 18v power adapter included with the sale. Also included is an extra top to the enclosure. This top is blank (no signatures) so you can take it out and use it without worrying about scratches or dings on the original. It is initialled on the inside by Todd Kelley, owner of Endangered Audio Research, and is marked #6 on the inside as well as the bottom. The number on the bottom is worn a bit, but is still there."

"The Endangered Audio Research Spectravibe is an all-analog multi-effect pedal that is about to become your pedalboard's new secret weapon. Based off the retired Gristleizer stompbox, the Spectravibe is a new evolution in modulation and distortion that is destined to become the pulsating heart of your rig.
In Trem mode, the Spectravibe acts like a tremolo and adjustable overdrive. Two wave shapes are provided: triangle and saw cover the most useful modulation needs. The frequency of the LFO ranges from 4 seconds to well into the audio band - much wider than any typical tremolo. Use the Depth knob to go from a slight warble to a total stutter, and use the Bias control to adjust the FET tube-style distortion. The Gain knob takes your tone from clean and subtle to in-your-face overdrive. In Trem mode, the Blend knob acts like an adjustable high-end air frequency booster. The two expression pedal controls for Speed and Depth allow you to keep
In Vibe mode, the Spectravibe is like vibrato or a Leslie simulator. The unique lush filter has an extended range that brings out the best of your bass, guitar, and keys. Use it on a send while mixing as a "secret weapon" EQ. Go from sweet and shimmery to a bubbly underwater sci-fi filter with the Depth knob, which controls the amount of frequency modulation. The Bias changes the filters center frequency and the Gain allows you to overdrive the filter. The Blend control will add back unfiltered signal that is essential for nailing a watery rotary speaker effect.
In both modes, you can bypass the internal LFO an inject your own modulation source. Use LFOs or envelopes from synthesizers for even more wild and unique effects.
The Spectravibe can be used purely as a versatile distortion box. Turning the Depth all the way down cuts off the modulation completely. The Bias, Gain, and Filter Mix can all be adjusted sans-tremolo for a wide palette of dirty tones. Add that to the high-level amp-driving output provided by the internal 18-volt circuitry, you can use the Level knob to rope in your guitar's preamp into your sound even more.
To use the Spectravibe as a Ring Modulator, set it to Trem mode and turn the frequency of the oscillator into the audio range. The Depth, Bias, Gain, and Blend knobs all interact in a way that make other Ring Mods seem stiff and unmusical. Plug in an expression pedal and you can control the pitch of the oscillator mid-solo. You can even use the Mod input to sync the Ring Mod with a synthesizer.
Great guitarists know about the parked wah tone trick - that is, using a wah-wah pedal as a band-selectable frequency controller. To do this with the Spectravibe, turn the Depth knob all the way down and sweep the Bias until you dial in the perfect tone. Turn the Blend knob all the way to the left to highlight the frequency band you want to boost. Once you've found it, start turning the Blend knob up to mix back in your original signal. Finally, use the Gain control to adjust the grittiness of the filter and the Level control for overall boost to get the perfect amount of bark. It's a tone tweaker's dream!
The Spectravibe runs off a normal 9-volt DC pedal adapter, but the circuitry inside boosts the voltage to +/- 9 DC for a total 18 volts. This is big: no special, expensive, and bulky adapters to keep track of, tons of headroom, and lots of gain. In fact, the Spectravibe has so much gain that you can use it as an interface between your guitar and a modular synthesizer. The switching supply Endangered Audio Research custom-designed for this pedal produces no audible whine that you'd find in cheap adapters. This means you can use any standard tip negative 9 volt supply!
With the versatility and analog tone this pedal provides, the Spectravibe will become the single most important pedal on your board - so important that you'll probably want two!"
"This video demonstrates several different ways to use the CV inputs of The Gristleizer Eurorack module by Endangered Audio Research. For more information about The Gristleizer, visit:
"Ableton Live is controlling the oscillator and the L-1 Tube VCA through the iConnectivity Box and the Expert Sleepers FH-1, and I'm scanning through different sounds and modes of The Gristleizer to show what a versatile tone box it is. Few modules can radically alter their input this much!"
"Here are a few clips of The Gristleizer working with some other modules. The Expert Sleepers FH-1 is acting as a bridge for my KMI QuNexus (off screen). The Disting mk3 is the oscillator, which is feeding into the L-1 Tube VCA, which itself is triggered by the gate from the FH-1 (I don't have an envelope module at the moment). The output of the VCA is then fed through the Gristleizer and sent through my Universal Audio Apollo, where a Cooper Time Cube provides the stereo delay. It is also running through the Neve 1073 Preamp plugin, the Studer A800, and the Ampex ATR-102.
0:00 - Output A of the Disting is multed using a Tiptop stackable cable to the Mod input of the Gristleizer in VCF mode. This means that the speed of the scanning Bandpass Filter within the Gristleizer is moving at the same rate as the pitch of the oscillator. Doing this, the Bias, Filter Mix, and Depth Controls all allow you to dial in amazing tones.
0:46 - This is the same setting as above, but the internal triangle wave of The Gristleizer is modulating now. I call this effect a phase ring mod. Although it does not use diodes in a ring configuration to achieve the ring mod effect, the effect of the scanning BPF creates another oscillating tone that, especially when dialed into the tonic or the dominant note of the scale you're using. In this case, I am dialing it in so that it crashes against the pitch of the Disting's oscillator, creating some truly growling tones.
1:46 - Here, I'm adjusting the drive of the VCA to create some feedback overtones in order to highlight the range that the Bias knob sweeps through. The Bias controls the center frequency that the Gristleizer sweeps through. Only with the Endangered Audio Research Gristleizer filter do you get this wide range - the original design was focused way down in the bass range which, for most instruments, was completely unusable. The redesigned filter is dirty enough to be at home within The Gristleizer, but is without a doubt much more musical. In this example, I have patched the Saw LFO output to the Mod input (breaking the normalized connection to the Triangle wave).
2:17 - This is The Gristleizer in VCA mode. Notice towards the end of this clip how much the Bias changes the tone of the input. The added Filter Mix control also doubles as a presence control in VCA mode. The Square LFO is patched into The Gristleizer's Mod input.
2:59 - Another example of the phase ring modulation effect."
Exploring The Gristleizer Eurorack Module - Part 2
"Ableton Live is controlling the oscillator and the L-1 Tube VCA through the iConnectivity Box and the Expert Sleepers FH-1, and I'm scanning through different sounds and modes of The Gristleizer to show what a versatile tone box it is. Few modules can radically alter their input this much!"
"This is a drone piece using three Eurorack Gristleizers. The one on the left is in VCF mode, while the other two in VCA mode with nothing plugged into their audio inputs are acting like VCOs. These two VCOs are sent through the VCF Gristleizer and into Ableton Live with a little Universal Audio EMT 140 Plate Reverb. The saw wave LFO from the VCF Gristleizer is fed back into the Frequency Mix input of the second VCO Gristleizer."
"This is a tabletop Endangered Audio Gristleizer feeding into an Erica Synths Fusion Series Tube Ringmod with the Eurorack version of the Gristleizer acting as the carrier, with some feedback loops thrown in. With the right settings, you can get tube glitch beats out of this setup - the Tiptop stackable cables seem like a no-brainer for anyone who likes to freely experiment with feedback. This is just 16 minutes of noise I'm making with them - skip around to hear how the sound evolves over time.
"In this video, I set up a simple 2 oscillator output from Audulus (no filters, no effects) - the majority of what you see on the iPad is the sequencer, clock, and the LFOs that are modulating various parameters.
The oscillators from Audulus are sent into the Endangered Audio Research Gristleizer, and then on into the Minimoog VCF through the external input (the oscillators and noise generators are turned off).
The output of the Minimoog is sent into the Endangered Audio Research AD4096 analog delay pedal.
Finally, the delay is routed into the Apollo 8 where, after passing through a Neve 1073 preamp and a Studer A800 tape machine, it is processed with the Slate VCC Neve Console, the Manley Vari-Mu Compressor and Massive Passive Mastering EQ, and finally the Ampex ATR-102 running at 3.75IPS and with a smattering of wow and flutter, and a bunch of stereo delay."
"The Minimoog is running through the Endangered Audio Research Gristleizer to an AD4096 analog delay (which will be for sale soon at Hey Day Music in Asheville, NC). It then goes into an Apollo 8 where it passes through a Neve 1073 Preamp to an Ampex ATR-102 set to 3.5IPS 456 formula with tons of wow and flutter.
For mixing, I used the Slate VCC Neve, the Manley Vari-Mu, Manley Massive Passive Mastering EQ, and finally back through another pass of the Ampex on 30IPS 250 formula."
"This video uses the ARP Omni to showcase the new filter in The Gristelizer v3 (same as in the eurorack module). The AD4096 adds some smeary reverb-ish background.
The recording was made using a Universal Audio Apollo 8 using these plugins: a Neve 1073 Preamp, the RCA Tube Slate VCC, Studer A800 tape machine, Manley Vari-Mu Compressor, Manley Massive Passive Mastering EQ, and the Ampex ATR-102 tape machine."
