We present the stunning and iconic early-1970s Arp 2600 semi-modular which contains the sought after (and so-called) pre-lawsuit Moog 4012 style filter. This instrument is around 45 years old and just looks and sounds absolutely amazing.

We previously sold this actual Arp 2600 Tonus back in 2009 to our client we are Brokering it for, so it’s great to see the synth back again looking so beautiful still. The ‘Total Restoration’ work restoration was also carried out in 2009 on this Arp, and covered all cosmetic and operations aspect of the synth, details as follows:

Notes on the cosmetic condition:

The control surfaces/panels on the synth & keyboard were stripped, repainted and screen-printed. The Tolex covering and bright-work was in need of restoration (as is common on the old Arp systems), so KSR re-Tolex’d both units, and replaced all the exterior nickel-plated components. The Keys on the 3604-P were in good shape, so where kept original to retain that authentic vintage ageing across the key-bed.

Notes on the restoration:

Aside the repainting, screen-printing, re-Tolexing and replacement of the exterior brightwork mentioned above, the operational restoration on the 2600 was extensive, and mostly all Arp 2600 systems we see these days need this level of attention. KSR had undertaken a complete ground-up rebuild of the electronics with full test and calibrations and PSU rebuild etc. Each and every slider was split apart, cleaned and rebuilt, every jack cleaned & tested, and a system-wide check of all connectors, and solder joints etc. The keyboard was stripped an completely overhauled, and new busting fitted etc. Where possible, all the original parts were retained to ensure continuity and authenticity but some ageing components like power conditioning caps have been replaced, but only were absolutely necessary.

In the last 9 years since the Arp 2600 was restored by us, the synth was used and kept at home with our UK client, who has taken great care of it. The cosmetic and operational condition is perfect and the same as the day we handed it to them.

This is a fantastic opportunity to buy one of the most iconic vintage synths ever made, and the price has been agreed with our client to keep it very competitive, and incomparable to any Arp 2600 being sold anywhere in the world right now…it’s a Total Restoration RL Music vintage synth, after all!

The original 3604P keyboard is useful, and is a historically correct partner for this model of 2600, and has had a modification to the output connector as you can see in the pictures. KSR actually implemented the DIN socket mod, which is a much more reliable connection than the propriety Arp block connector which was always a weak link in the chain we have found. in reality, the 3604-P offers limited access to the extensive inputs into the main synth, so to get the most out of the 2600 we would recommend using a multi-channel Midi to CV device like the Kenton Pro-2000 which can give you 3 note polyphonic control if needed. We can supply a Kenton Pro-200 but is not included in the sales price below, so please ask us for prices.

These outstanding synthesizers are hard to find in decent condition, so here is a rare opportunity to own a superb fully professionally restored example that will only appreciate in value and add something special to your studio.

Supplied with all (restored/Tolexed) lids and DIN CV/Gate interconnect cable. The Arp runs on EU 220V via a standard IEC power connector. We will also supply an Arp 2600 owners manual (PDF).

As with all Brokered Sales, the Arp 2600 will be fully serviced post-sale before it’s sent to its new owner, although this synth really only needs a ‘health-check’ as it’s in such good condition throughout. We do this to ensure that the instrument leaves us in perfect operational condition, and it is backed up by our full 3-month warranty to give the new owner complete peace of mind. The servicing is carried out as a priority once the sale has been completed, and although it will delay shipping/delivery by a short time, we know from experience that customers are happy to wait.

Price: £7990 GBP.

Availability: This Arp 2600 Tonus is now SOLD as at 23rd March 2018.
