"Peruvian semi-modular analog synth with an absolutely INSANE sounding filter.. This synth can easily allow you to take Acid music to a whole new level of crazy. It's in abolutely MINT condition, it even has the protective outer film layer on it still. 100% fully functional and has been used for less than 2 hours in total. The power supply is included but you need to get a very common cord for it. It's same type of cord that's used for various rack gear & old school computers. Should be easy to obtain. the last pic shows you the style of cord it uses."

"A basic synth with a WILD vactrol acid filter. The "4 + >" button doesn't work very well when pressed in it's center but works fairly ok if you press down on the top edge of the button at an angle. All other buttons work fine, knobs are all good, Screen is crisp and bright & synth engine is fine. There are bubbles in the clear plastic body parts & a black scuff on the green face plate. No power cord included but it's a very common type of cord, easily obtainable."

"If you’re looking for an RA Moog–era Minimoog Model D on a budget, this is a great opportunity. The previous owner replaced all four of the original mainboards with new units from SynthRestore.co.uk; unfortunately, the original boards have been lost to time. While this does impact the instrument’s value from a collector’s standpoint, it is fully functional and performs reliably.

The exterior cabinet is in excellent condition and may have been rebuilt or replaced, along with a fresh set of knobs. Overall, it’s a fantastic player’s instrument with vintage character at a more accessible price.

Serial No. 1117"

"The Moog Memorymoog Model 345A is an early-production version of Moog’s flagship six-voice, three-oscillator-per-voice analog polysynth from the early 1980s. It delivers the same massive, layered sound the Memorymoog is known for, combining classic Moog filters with extensive modulation. The 345A designation mainly reflects internal production labeling rather than a feature difference. Today, it’s regarded as one of the most powerful and collectible analog polysynths ever built. This one was just serviced by our in-house technician...

Service notes:

-Installed kenton midi retrofit kit
-Modified bottom panel and keybed frame as per instructions
-Fitted midi jacks and push button switch to reaer panel
-Recalibrated entire unit and bench tested for several hours"

"The Jupiter 6 is a fantastic analog polysynth that's a little bit of an underdog compared to its siblings the 4 and the 8! However, it is very powerful and is likely overlooked due to the immense fame of the others. Its a dual VCO 6 voice with cross mod capabilities, sync, and triangle, square and saw waveforms. The filter section includes standard low pass but also band pass and high pass operation.

The filter envelope routing is not preset so envelope 1, 2, or both can be assigned to control the it! The LFO section is fully featured including a random output and onset delay. Of course there is full preset saving and plenty of performance oriented controls. The one downside is that it does not include chorus or ensemble like many of the other Roland polys! It does have the coolest color scheme and those futuristic aluminum sides though. The external analog ins include arpeggiator clock in, patch shift, pedal hold and CV for the VCA and VCF. Of course it has MIDI as well so there is tons of interfacing available.

This synth is in excellent working condition and was recently serviced by our in-house technician. It arrived at our shop in need of a little TLC, and it has since received several replacement potentiometers and sliders. A few knob caps are mismatched in color, but these cosmetic quirks have no impact on its performance. Everything has been fully tested and is functioning perfectly.

It has a replacement keybed so you'll never have to worry about the red glue problem that these all eventually fall victim to.

It's got a few scuffs and scratch on the display but overall it's in great functional condition."
