PRODUCT DESCRIPTION

A rare chance to get your hands on an early Arp 2600 “Tonus” in superb condition and excellent working order. Option to swap the keyboard for a later duophonic model (see below).

Soundgas-serviced/calibrated by our head synth tech, James Walker. The synth is performing very well and will have a final tune-up/calibration before we ship out; the keyboard has been fully-overhauled and plays well.

Description

Video demos below!

Rare chance to acquire a celebrated c1972 Arp 2600 “Tonus” which was previously restored by a noted US synth specialist; further servicing and calibration carried out by our chief synth tech, James Walker. It comes with the correct 3604P keyboard, but the buyer can elect to swap this for the later duophonic 3620 keyboard, if required (the latter keyboard has not yet been serviced so this would delay delivery). It will ship fully-serviced and calibrated and with our usual guarantee. This synth is in excellent condition and very sweet indeed. Tonus 2600s are highly-prized by synth aficionados and are becoming harder to find in good order. The synth has had a CMS4012 filter module installed – Phil Cirocco of CMS makes the best upgrades and replacement parts for Arp 2500 & 2600s.

CHOICE OF KEYBOARD: It comes with the correct early keyboard, but the buyer can elect to swap this for a later duophonic 3620 keyboard we have available (the latter keyboard has not yet been serviced so this would delay delivery).

It will ship fully-serviced and calibrated and with our usual guarantee. This synth is in excellent condition and very sweet indeed. Tonus 2600s are highly-prized by synth aficionados and are becoming harder to find in good order.

This will be extensively tested and recalibrated by our resident synth wizard before it leaves our hands. All features and functions are working as they should, but this is a handbuilt vintage synth and it is possible that some recalibration may be necessary once it has shipped. It is also possible that the odd slider or switch might crackle if the unit has not been used for longer periods, but this should quickly clear with use. This is all standard stuff and doesn’t in any way absolve us of our responsibility to deliver to the buyer a superb Arp 2600. If you have any doubts or questions, please do get in touch.

===========

Exactly what “version” 2600 is it? Is it one of the “good” ones? 

Like many early synth manufacturers, Arp production was fairly chaotic. While some sources online will say that this or that version sounds “better” or “best”, the reality is that variations are common between modules, even if they were made the same year, due to manufacturing/component inconsistencies. The timeline of production for the various models is not perfectly chronological. Like most smaller gear manufacturers of the ’70s, Arp didn’t operate on a rigid structure and to suggest that 1970s hand-built synths have similarly linear/traceable timelines to those made on a modern factory production line is somewhat divorced from reality. And not all synth techs are equal: previous restoration/service work plays a part in the performance of a vintage instrument. As a result, there can be good or less good examples across all years of production or, as one Arp engineer put it, some units have just ‘got more soul’
If you want to delve deeper, Phil Cirocco’s excellent site is full of detailed info/history and is the foremost resource for ARP synths and modifications.

The front panel, controls and keyboard are all superb with only minor signs of wear or age. The keys of the 3620 keyboard are showing some age in terms of fine scratches and scuffs but overall this is also is excellent condition. The tolex has some wear and scuffs – mostly on the edges – but nothing serious. Overall this is a great example of an exceptional instrument. See photos for more information on cosmetic condition.

If you want more background the Vintage Synth Explorer’s ARP 2600 page isn’t bad (at least they give it 5 stars!).

TESTIMONIALS

“I have bought two Moog synths from Soundgas over the past year, and I cannot say enough wonderful things about their selection of vintage products, the level of service, diligent responses to email, and expedient shipping with copious protective packaging. Soundgas is an impressive operation. My synths also sound amazing! These folks have made my vintage keyboard dreams come true in short order!”

J Yates

“If you are a vintage audio gear head then this is the place you have been looking for all your life. Pretty much any piece of classic or obscure kit that you are after is available here... But the clincher for me is that the gear they sell has been restored by their top techs (unless otherwise noted) which is really very important when dealing with, for example, synths from 30 years ago.”

Lincoln Barrett / High Contrast

“Imagine the perfect eBay.... with everything you never knew you wanted… and you can rest assured that your vintage and rare wobbly sound device will turn up on time and in one piece and possibly in even better condition that when it left the workshop. Soundgas - literally amazing."

Josh Lloyd-Watson & Tom McFarland - Jungle

"The packing job to get it over to the US was superb, and the sound and performance of my Space Echo exceeds all of my expectations. I hope to do business with Soundgas again in the future. Many thanks!”

Tom Rowlands - Chemical Brothers

“I’ve bought a number of items from Soundgas recently, and have been really impressed with their service. It takes the stress out of buying vintage gear to know it’s been properly (and faithfully) serviced or restored. Their after-sales service has also been exemplary. Highly recommended.”

David Wrench

Ben Van Vlissingen

Tucker Martine - Flora Recording

“I purchased a completely overhauled vintage valve Binson Echorec 2 T7E modified with varispeed, wet-only output, and a new paint job from Soundgas in early 2018. Tony and his team did an amazing job during every step of the purchase”

Matt Morton

“The perfect place to hear, learn about and then buy your most wanted piece of vintage music gear! I've not only managed to buy a rare piece of equipment I really wanted, but I have the guarantee it's been serviced, and I got it from people who are clearly passionate and knowledgeable about what they do, as well as super friendly and responsive by email. Thoroughly recommended!”

James DLR - Sofa Sound/Metalheadz

“If not a new language, then at least a very challenging, old dialect that will take me some time to assimilate. I’ve been waiting a long time for the challenge. Thank you @soundgasltd, she’s a beaut...and nobody prepares and packs like you fine folks.”

Justin Meldal-Johnsen

"Excellent equipment, wonderful service. I fully recommend Soundgas to anyone in the vintage gear market and I will definitely be a return customer. The gear itself was exactly as advertised and in great condition."

Koko Hiras

"DREAM. COME. TRUE. My music has taken me around the world a few times...and if you are like me and absolutely adore vintage gear...Soundgas is the stuff of LEGENDS. It's the shop that people like us search for our whole lives- fantastic and rare selections, and the technical know-how to repair and or mod these vintage items to get them into shape to flow with your modern setup."
