🙋🏻‍♂️ Welcome and foreword

Hello dear musician friend and welcome to my Reverb Shop! I am glad that you are interested in this article. Be sure that each of the instruments offered is in very good and tested condition. Everything comes from my private collection and is treated with a lot of love and passion.

I am aware that I am one of the higher-priced providers, but I really try very hard to present the devices very transparently and also to make you, the buyer, happy. The packaging of an item takes me between 2-4 hours because I double and triple secure everything to ensure carefree transport. The quality of the instruments and my work is my number one priority! I am always available if you have any questions. I hope you enjoy reading the description.

🎹Information about the item for sale

Iam selling a beautiful Ensoniq ESQ-1 Wave Synthesizer. The synth is in very good condition and works perfectly! There are minor signs of using but nothing wild. Its full cleaned inside and outside. It comes with a Catrige and the original Ensoniq hardcase. The Synthesizer got a new original Panasonic 3V BR-2/3A and was again reseted and calibrated. It got also a nice Sequencer Expander catrige.

Here are some facts about the synth:

Ensoniq ESQ-1 is a 61-key, velocity sensitive, eight-note polyphonic and multitimbral synthesizer released by Ensoniq in 1985. It was marketed as a "digital wave synthesizer" but was an early Music Workstation. Although its voice generation is typically subtractive in much the same fashion as most analog synthesizers that preceded it, its oscillators are neither voltage nor "digitally controlled", but true digital oscillators, provided by a custom Ensoniq wavetable chip. The signal path includes analog resonant low-pass filters and an analog amplifier.

The synth also features a fully functional, if crude by modern standards, 8-track MIDI sequencer that can run either its internal sounds, external MIDI equipment, or both, with a capacity of 24,000 notes (expandable via cartridges). It provides quantization, step-editing, primitive forms of copy/paste editing, and can be synchronized with external MIDI or tape-in clock.

ESQ-1 can store 40 presets internally, and features a cartridge slot for additional storage capability. ESQ-M, a rackmount version of the synthesizer, was released circa 1987, with the same specifications but without the sequencer.

Notably, the sound chip at the core of the synth, the 5503 Digital Oscillator Chip (DOC), is a brainchild of Robert Yannes, father of the popular Commodore SID chip.

I would really appreciate it if you read everything :) More information about buying from SynthFreak!

📹 Video before & after the purchase

Any interested party will be happy to receive a video of the instrument on request. Pictures say more than 1000 words but a video probably even more! So that you can get a better picture of the device on offer, I offer all my interested parties a video of the device. Every buyer also gets a video of a detailed check UP before shipping. So you can look forward to your device even before it is shipped and received and you already have a first glimpse of your new instrument. If I notice during the check that something is not working properly, the device is immediately handed over to my technician for repair.


It is very important to me that my devices come into good hands! If you can't spend that much money right now, due to the current economic situation regarding the pandem.. In all of my offers, I offer the option to send me a price proposal. If you are really interested, just send me an offer, if this is possible, I will of course accept your price proposal.


All my synthesizers and keyboards come from my private collection, which is constantly updated. All devices are thoroughly cleaned, disinfected and tested! Every device that is for sale is taken from my collection and already wrapped in foil to avoid dust deposits and other soiling.


It is very important to me that you as a customer are satisfied, and that your ordered instrument is intact and in top condition arrives at you. I attach great importance to safe packaging because you never know how the parcel delivery service will handle the parcel. For this reason, I pack every instrument in a very safe way so that everything arrives undamaged and we are both satisfied. Take a look at my "SECURE PACKAGING" now!

💢Shipping during pandem.

Due to the pandem. it has become much more difficult and expensive to send parcels abroad! Since the pandem. measures change regularly, I always look for the best, fastest and safest shipping service for you so that you receive your instrument on time. With me you can be sure that you will receive your package even during the cov. pandem.

⚡Power and connection

My instruments come from the EU, so the power cable is also equipped with an EU plug. If you live in a non-EU country, it is possible to use different adapters for the power connection. It is also often possible to set the transformer to the voltage of your country, or you simply use a current transformer which is often offered on the Internet for 30-50 €.
