"For sale is this vintage 1970s Multivox MX-450 Pedal Synthesizer. This particular example, serial number 00476, is in nice all original condition. Though there is slight cosmetic damage on the right side of the particle board panel, this unit works absolutely perfectly and sounds i-n-c-r-e-d-i-b-l-e. Surprisingly versatile, this simple monosytnh produces rich guttural grain and badass bass. Easy to use, and undeniably addictive, this is a must have for any and every modern studio, producing sounds that will find their way onto a plethora of tracks. Of all the cool Multivox keyboards from the '70s, the MX-450 happens to be the favorite, and aside from the obvious Moog Taurus bass pedals, this is the hands down the coolest pedal synth.

White MOOG LIBERATION KEYTAR SN 3282

"Extremely rare white Moog Liberation Keytar circa 1980. Unit works 100% takes a few minutes to warm up and for the ocs. to stabilize, and contacts could use a little spray, but everything works as it should. The sound on this synth is unreal. The bass sounds surpass the minimoog in my opinion. Technically there are 5 oscillators on this synth, and stacking them gives you an unreal fatness that you simply cannot find in any unit currently on the market. Case exterior is battered, but all the latches work and the interior is fine and it holds together..."

Note the listing mentions they will provide a can of deoxit for the sliders. This is not recommended as long term it can damage the synth. You can read up on cleaning the sliders here. Also see the video just posted below.

How to Rebuild ARP Sliders

Published on Mar 19, 2013 New England Analog LLC·9 videos

"This video is a short tutorial explaining how to restore ARP sliders. We see many people spraying them out with deoxit, which usually only worsens the problem. To truly restore the feel of these sliders, they must be removed from the board, cleaned, and lubricated.
Sorry for the poor videography. The video was done on a whim to help somebody across the country who wanted advice."

ARP 2600 Fully Restored with Mods

"Many hours have been spent in upgrading the audio and cv path in critical areas.
Part of the list;

It was changed every 1/8" jack.
New and larger spring tank rever with lower noise circuits.
New power supply stable and accurate international power linear supply, currently, the AC input is hardwired for 230 volts.
Unit will operate with 220, 230 or 240 volts AC, but internal jumpering is possible for 110 operation.

The filter is an unmodified ARP 4012 design, (the MOOG FILTER).
The internal amps are modified for lower noise and faster slew rates.
1/4" output jacks, these jacks carry the left and right signals as provided by the output pan mixer, same as the 1/8" jacks below them.
The envelope generators have been modified. Lower offsets( output voltages when not being used) than stock. The AR gen has considerably fasters attacks
and added gate input not normally provided by Arp.
The ADSR has much faster decay and release times available than stock.
The gate button is a high reliability type ( used in Neve and Api consoles) and provides a larger surface and a softer feel tahn stock, in addition to lightning up with a gate signal.

COMPARATOR.
This circuit mod takes its input from the envelope follower input jack (not the EF output jack) and produces a very fast risetime gate for its output. This gate is dependent upon the level
of the ipunt signal and the setting of the threshold control (grey knob). The blue Led provides visual status operation.

LAG PROCESSOR.
This circuit has been modded so no offset voltages are present during usage. Can now be used for pitch voltages (glide) without tuning
problems when adjusted, can smooth out gate signals from the comparator gate output...etc."
