It appears to have an original red Surrey Electronics case, compared to this racked one. You'll find a spec sheet there as well.
"Surrey Electronics Spectrum Shifter
Uses the same principle as Bode frequency shifter. Ostensibly for 'Howl Reduction' but capable of some very interesting effects. Essentially, unlike a pitch shifter, a frequency shifter does not preserve the harmonic relationships in the input signal. In practice this means the output quickly starts to deviate from what is going in and extra tones are added which then interact and interfere with the source producing new harmonics and drones. Very good with other fx. Great studio addition as you can plug allsorts in not just for vocals.
31cm x 27cm x 24cm
240v unit
Mono input and output via 1/4" jacks on the rear. (standard 'guitar' Jacks)
some scuffs and slider plastic is missing, did not replace as does not affect use. See photos."

No computers, no plugins, just pure hardware (with a touch of bit-crushing) and hands-on performance.
Watch as layers of classic synths bring new life to one of the most recognizable themes in video game history, with quick cuts showcasing the instruments behind the sound.

And one from Starsky Carr:
Analog Done Right // GS Music Bree 6 Keyboard
video upload by Starsky Carr
"In this in-depth demo and review, we explore the GS MUSIC Bree 6 keyboard — a 6-voice VCO-based analog synthesizer with a fully analog signal path, built-in chorus, delay, arpeggiator, and sequencer. If you love that vintage-meets-modern sound, this one might surprise you.
From raw oscillator tones to lush stereo pads and punchy basses, I break down what makes this synth special — including its unique double/triple arpeggiator modes, MPE compatibility, and rich, characterful sound that sits somewhere between classic Roland-style synths and something entirely new.
If you’re into synths like the Roland Jupiter-8 or Roland Juno-106, this is one you’ll want to hear.
๐ What’s Covered
Sound demo (full track made entirely on the Bree 6)
Oscillator section: saw, pulse, sub oscillator
24dB analog low-pass filter with resonance & key tracking
Dual ADSR envelopes & fast modulation
Voice modes: poly, mono, unison & stereo spread
Built-in chorus & analog-style delay
Unique arpeggiator (double & triple note modes)
Sequencer workflow & performance features
MPE support & expressive control
๐️ This isn’t just another vintage clone. The Bree 6 blends:
Raw VCO tone with modern reliability
Hands-on workflow (minimal menu diving)
A distinct character that feels alive and immediate
A surprising amount of depth for a single-oscillator synth
๐ง Who Is This For?
Analog synth lovers
Producers looking for fat, mix-ready tones
Fans of classic Roland-style sound with modern features
Anyone wanting a hands-on, inspiring instrument"

The day has arrived
We’re proud to present the Bree6 Keyboard, our first synthesizer with an integrated keyboard, designed and produced in Argentina for the world. ๐
Built on a six-voice analog architecture, it delivers a powerful and expressive sound engine capable of everything from solid basses and leads to rich, evolving pads. Now expanded with a built-in sequencer and advanced arpeggiator, it becomes a complete performance and composition tool.
With its one-knob-per-function interface, semi-weighted keybed with velocity and aftertouch, and fully analog signal path, the Bree6 Keyboard is designed for immediate, hands-on control—no menu diving.
Immediate Control. No Menu Diving.
The Bree6 Keyboard version is designed to deliver an immediate and intuitive hands-on experience, eliminating the need for deep menu navigation. Its interface follows a one-knob-per-function philosophy, providing direct access to all key parameters for fast and precise sound shaping.
Introducing Cre8audio Programm - MIDI and CV Sequencer
video upload by Cre8audio
Check with dealers on the right for availability.
"As electronic musicians, we’ve used every sequencer under the sun. We loved the speed of some and the randomness of others, but we hated having to choose. So, we built PROGRAMM.
It’s a creative playground that bridges the gap between human performance and algorithmic generation. Whether you’re meticulously stepping in/playing a melody or using real-time randomization to find new textures, PROGRAMM keeps up with your brain. And for those moments where you accidentally forgot to hit record before playing the best sequence you’ve ever written? We built an always-ready recall function to save your soul (and your track)
Total Versatility: Step it in, play it in, or let the machine take the lead.
Controlled Chaos: Dive into deep generative tools and real-time randomization that stay musical.
Are you bilingual? Programm is: MIDI and/or CV Programm loves both!
Be hands-on (and quickly) - with its 6 orange knobs you can tweak the main parameters per step with speed and without menu diving.
PROGRAMM is built for the sketch and the deep dive. Fast enough for your first idea, deep enough to take you the whole way."
