🙋🏻‍♂️ Welcome and Foreword

Hello and welcome to my Reverb Shop!
Thank you for your interest in this listing. Every instrument I offer comes from my private collection and is treated with great care and respect. Each instrument is thoroughly checked and tested to ensure full functionality and excellent condition. Before any instrument is listed for sale, it goes through a professional multi-stage inspection by our technician. Only after successfully passing all functional and visual checks is it approved for listing.

I am aware that my prices may be above average, but this reflects my commitment to transparency, careful preparation, and customer satisfaction. Packaging alone takes 2–4 hours, with multiple layers of protection to ensure safe and worry-free transport. Quality — both of the instruments and my work — is my top priority. I am always available to answer questions and ensure a smooth buying experience.

Enjoy reading the description.

🎹 Information about the Item for Sale

I am offering an absolute legend of the late 1970s: the ARP Quadra. Produced in limited numbers between 1978 and 1981, the Quadra is one of the most iconic, visually striking, and sought-after analog multi-synthesizers ever created. It combines four independent, classic ARP engines into one massive, orange-and-black performance powerhouse.

The Quadra is famous for its symphonic, layered capability, allowing you to combine:

• A deep, punchy, dual-circuit Bass Synth (lower 2 octaves).
• A lush, rich String Synth (derived from the legendary Omni series).
• A flexible polyphonic Poly Synth section with its own dedicated 24dB/octave ARP 4075 low-pass filter.
• A screaming, duophonic Lead Synth with aftertouch expression and interval memory.

All of this runs into a spectacular, built-in Voltage Controlled Stereo Phase Shifter that gives the Quadra its signature shimmering, cosmic texture.

Technically, this ARP Quadra is in excellent functional condition. Anyone familiar with these instruments knows how finicky their vintage touch-panels and microcomputers can be—this unit has been thoroughly and professionally inspected. All sliders move smoothly, the keys respond beautifully (including the lead section's aftertouch), and all four sections mix perfectly. Optically, it shows normal, light signs of use consistent with its age, but retains a magnificent, well-preserved presence with its classic "leather-look" orange end blocks.

Please note: This listing includes the ARP Quadra and the power cable.
