Vintage ARP Odyssey Mk II Synthesizer w/ New Yellow Capped Sliders & Moog Ladder Filter

"The Odyssey was ARP's answer to the Minimoog, a feature packed scaled down version of the legendary ARP 2600. This particular ARP Odyssey is equipped with the 4035 filter, the infamous "lawsuit filter" that "borrowed" from Bob Moog's ladder filter patent.
This ARP Odyssey has just been serviced and is functioning very well. New sliders & slider caps were installed, power supply recapped, all tantalum capacitors replaced, new slide switches, new key bushings, cleaned key contacts, calibrated, and the 1/4" output jack made to a high output.
There are a few flaws I feel the need to disclose: This particular Odyssey has a fairly high noise floor. You can hear it (white noise/hiss sound) when the tone sources are turned down and the VCA is open, or if the filter isn't fully open. Also there is some slight bleeding of the tone sources into the final output (bypassing the VCF). Please see the attached video for a demonstration of this. There are some large scratches on the front panel, see photos. Since the cosmetics of this Odyssey aren't perfect, I decided not to invest the time into fixing these last problems and instead just offer the synthesizer at a better value."

Vintage ARP Odyssey Mk II 2813 Synthesizer w/ LED Sliders & Moog Ladder Filter

This ARP Odyssey has just been serviced and is functioning very well. The Synthchaser LED slider & slider cap set has been installed, and the LEDs are color coded to correspond to the original colored slider caps, which give a visual indicator of the function of each control. The difference in the way these sliders feel and perform compared to the originals is a huge improvement. The power supply was recapped, all tantalum capacitors replaced, new key bushings, cleaned key contacts, calibrated, and the 1/4" output jack made to a high output.
There are a few flaws I feel the need to disclose: The old silkscreen was worn away and the paint was also worn through, so I've installed an overlay. The quality of the overlay isn't the greatest, and the color doesn't quite match the rest of the synth, but anything is better than the way it was! Please review photos carefully. This particular Odyssey has a fairly high noise floor. You can hear it (white noise/hiss sound) when the tone sources are turned down and the VCA is open, or if the filter isn't fully open. Also, the ADSR modulation to the VCF can "overdrive" the filter if the slider is up all the way. Please see the attached video for a demonstration of these. There are a few extra holes on the back panel (the larger ones have been plugged) from previous mods that have been reverted. Since the cosmetics of this Odyssey aren't perfect, I decided not to invest the time into fixing these last problems and instead just offer the synthesizer at a better value."

AJH Synth Modular Sound Demo by @DKS SYNTH LAB (MiniMod Eurorack Modular jam, No Talking)
video upload by AJH Synth Official
"A repost of a video by Daniele Chierichetti demonstrating lead sounds and showing some of the sonic possibilities of an AJH Synth Eurorack modular synth system. The standard MiniMod voice forms the basis of the system featured here, and this voice is directly based on the original R.A.Moog version of the Minimoog, and as such it is capable of the same classic lead sounds, the same warmth, punch, and character. However, because it is modular, it takes this voice way beyond anything it was originally capable of, opening it up to the now huge Eurorack universe, including a wealth of modules by AJH Synth.
These high-end modules are mostly based on classic vintage designs, some of which are very difficult to obtain nowadays, but brought firmly into the modern Eurorack era by a wealth of connectivity, functionality, and reliability, that simply didn't exist 'back in the day'. Also, some modern, digital modulation modules compliment the range, hugely expanding it's sonic scope."
