Formanta Esko-100 Soviet Vintage Analog-Digital Delay/Echo/Fuzz/Oktaver/Way-way

Please read all the way to the end

ESKO-100 has been made in 1980x in the USSR, at the same factory as the famous Polivoks synthesizer.
It has warm and fat effects, good for guitar or vintage keyboards!
Unit's sound very experimental, interesting and in some applications even noisy, 
but sound is really unique - just like from 60s and 80s!

After playing on this device, I made some conclusions about what you can get from it: First fat fuzz, very wide sound, Very long Delay, reverb, A very wide variety of sounds, for games, special effects, SFX, horror films, etc. Even with the help of one guitar. Wide range of applications. I recorded a homemade demo, where I demonstrated the abilities of this delay. You can stick in it for hours.

You can also hear some noise in the video. Part of it creates my poor quality cable

The effects unit has a microphone channel (M) and an electric musical instrument (EMI) channel with effects for electric guitar, line input\outpet
and each channel has two inputs and an output.
The effects unit contains a digital electronic single-channel reverb with controls:
- recording level;
- volume of room modulation;
- signal decay time.
In the reverb, switching modes of operation are possible:

- Memory Enable (infinite repeat);

- "FLANGER" mode;
In the "FLANGER" mode, you can change the Depth and Frequency of the modulation.
The effects channel converts the electric signals of the guitar, allowing you to achieve such original sound effects as:

- "FUZZ" mode, obtained by turning on the corresponding switch button.
At the same time, the signal from the pickups of the electric guitar is amplified and limited, which creates a characteristic sound,
already widely known under this name;

- "Octaver", obtained by simultaneously pressing the "FUZZ" and "O" buttons.

In this case, an octaver effect is applied, and the volume of the sound is determined by the volume of the guitar;

- "SHMITTER", obtained by turning on the "FUZZ" and "SHMITTER" buttons.
In this case, higher frequency harmonics are added to the sound of the FUZZ.

When playing the guitar in FUZZ, ORGAN, SHMITTER modes, it is recommended to extract the sound in the middle of the sounding part of the string,
and move the switch on the guitar to the position corresponding to the lowest register or the maximum output signal;

- "VIBRATO" obtained by pressing the "VIBRATO" button.
In this case, the signals from the guitar in any of the above modes are modulated with a low frequency tone of approximately 5-15 Hz;
the modulation depth and frequency of the VIBRATO generator are set by the respective DEPTH and RATE controls;

- "TIMBER VIBRATO", obtained by turning on the pedal with the PEDAL toggle switch and the "VIBRATO" and "SHMITTER" buttons.
The depth and frequency of the Timbre Vibrato are set by the DEPTH and RATE controls;

- WAH-WAH (WOW, WAU) effect obtained when the expression Pedal is turned on with the PEDAL toggle switch.
The control of the tuning range is carried out within narrow limits and smoothly by a pedal,
within a wide range by switches, on which the frequency range is conventionally shown by musical notation.
The WOW effect can be used simultaneously with all effects.

Delay - modulation freq. min/max, modulation depth min/max, flanger/reverberator, record/memory.

Way way pedal works with all effects

This device is fully functional correctly. I received this device in excellent cosmetic condition. No one but me looked into it. Esko-100 Serviced and has an authentic appearance. Nothing has changed. Only the capacitors have been replaced and the input channel of the guitar and the line input have been adjusted. Now they have a normal signal level.

Cosmetic condition can be described as "A-"

There are a couple of scratches and scuffs in one place. Otherwise, ideally. Selling the whole set with original case

All functions work.

All metal construction and very heavy!
Weight approx. 8.5 kg !!! (about 13kg with package)
