ARP Quartet

“I have owned this ARP Quartet from new and it has been well looked after and the condition of the wooden and metal casing and paintwork is very good for the age. It has always been stored in its original box but the box is looking very worn now. There is a small area of flaked off paint on the rear of the keyboard that is visible in one of the photos. The sound is very good but there are two issues that i can see that you might want to get sorted if you purchased the keyboard. The volume slider dosen’t adjust the volume any longer so i adjust the volume via my amp so i have never bothered to get it fixed. All sounds and effects work except for the celest on the organ section. The slider has come loose and the celest sound is permanently off. This might need a new switch fitting.”

“Quartet ARP Vintage Synthesizer. Condition is used. Been stored for some years but is working well. Item is rare. The appearance has some cosmetic blemishes due to age and it would benefit from a service. The ARP is identical to the Italian made Siel Orchestra. 4 part orchestral synthesiser with four sections – brass, strings, organ and piano.”

“Very good condition as seen (just a few small scratches), has back panel CV/gate controls. CV = 1V/Oct, Gate = +15V. Note: the octave switch had been replaced by a three-position knob, this is actually more robust and easier to use than the original design, for fast range switching while playing live. Has the nicest sounding filter especially at high resonance levels among several whiteface Odyssey’s we’ve encountered, perhaps because it’s been very well calibrated. Hate to see this one go!”

ARP Quartet Project Machine

“ARP Quartet keyboard & string machine, classic fully-polyphonic machine from the 80’s pre-MIDI era. This unit won’t power up – it worked until going into storage several years ago, so I suspect someone who knows about electronics can resurrect it, but that’s beyond my ability. There is some slight gig damage to some of the switches on the front. You can select from brass, strings, organ and piano on the front, but by pushing the buttons together, you can have any two in combination. If you can get it working.”
