# Moog MG-1
“Moog/Realistic MG-1 Monophonic Analog Synthesizer
Up for bid is a Moog MG-1. This one works perfectly, but the cosmetics are not perfect – I’d say a 7.5 out of 10. There’s some slight cracks in the plastic overlay panel, some nicks and bumps, and a tiny chip on the back left of one of the plastic side cheeks – pretty unnoticeable.
All keys, sliders, pots, and switches work cleanly and clearly. I’ve checked out all the functions and everything works correctly.
I’ve performed the following maintenance/improvements:
* Cleaned out the horrible foam that destroys the sliders,
* Replaced all the sliders with new ones from Technology Transplant,
* New thermal coupling compound underneath the VCO ICs for better thermal coupling to the thermistors (better pitch stability),
* Replaced all the electrolytic capacitors with new ones of same or higher voltage rating,
* Recalibrated the synth per the service manual.
I’ve also made several modifications to this unit; most of these are very basic but very useful:
* Removed the silly RCA jacks on the back
* Replaced those jacks with new Switchcraft ¼” jacks for:
o Audio Out
o Audio In (to VCF/VCA)
o Gate In (positive voltage trigger > 1V, a more common standard in the synth world than the Moog S-Trig)
o VCF CV In
* Removed the tattered ‘Realistic’ label on the back panel
* Replaced the attached power cord with a more convenient 3-prong IEC connector (easier to transport, easier to store)
* Replaced the red LFO LED with a bright blue LED
* Added ‘Sync Sweep’ functionality
That last modification is something that the MG-1’s sister synth, the Moog Rogue, had, but was left off the MG-1. Here I’ve added a simple switch to the left cheek panel to allow you to switch the Contour (aka Envelope Generator) to sweep the pitch of Oscillator 2. When the two oscillators are not sync’ed, you get Osc 2 pitch ‘swoops’, but when they are sync’ed, you get very cool metallic dynamic timbre changes.” Link
