" Fully Restored and 100% Functional
For sale is a vintage ARP Quadra synthesizer. These are rare synthesizers, and even more rare, are ones that work. The Quadra is loaded with sensitive logic circuits, CMOS parts, and tantalum capacitors that number in the hundreds. We have spent countless hours restoring this synthesizer to like new condition. Most boards in this synthesizers have had all chips, capacitors, and resistor arrays replaced.
A custom 5 octave touch sensor was installed to give aftertouch capability over the entire range of the keyboard. We have also added mahogany sides to the case of the Quadra. It would be difficult to find a Quadra in better condition than this one. This item weighs around 90 pounds when shipped in its case. It will ship via UPS 2nd Day Air. The dimensions of the box will be roughly 50"x30"x16". The packaging and materials, plus one hour of labor to pack the item will cost $120. This will be added to the actual cost of shipping.
