“Nice MG-1 in excellent cosmetic and working condition. I purchased it from the second owner in the early 2000’s and rarely ever used it much. All switches and sliders work beautifully, without any hang ups or static. Even the headphone jack works fine. One slider tip is missing as pictured. Will ship to a USA address only.” Click here to search for synths on eBay

“Roland TB-303 Bassline. Fully functional and ready to ship. 
“Listing is for the CLASSIC Roland TR-808, I have owned this machine since 2004, and have put no more than 10 hours on this machine.
” Offering a Roland JP8000 keyboard synthesizer in clean condition. Lightly used and in good condition. Lights up. says battery low. Has problems with output, was returned due to issues that need attention. All keys seem to work. Joystick not responding. IT NEEDS WORK . Be aware of this. U FIX. Has power cord. No manual.SOLD AS IS, good luck.”
“Hi there – we have an awesome rack-mount synthesizer up for auction!
“Normal operation of buttons and sliders, sound output,
” This item does have some scratching from use but is still in good working condition. It comes with a old Hybrid case that has seen better days but still serves its purpose.”
“I bought this synth second hand around 5 years ago and it’s only had light home studio synth use while I’ve had it. It’s in good condition and the keybed is particularly nice to play (far superior in my opinion to my brand new Nord Lead A1!). A couple of things to note, neither of which have proved problematic for me. Firstly there’s a small audible crackle when changing the volume slider (typical on synths of this age). This is not an issue in operation as it’s literally only when changing the volume via the slider. Secondly the octave up and down buttons don’t respond (and never have while I’ve owned it). This hasn’t been an issue for me either – though I guess it’ll depend how you intend to use it (I’ve often had it connected via midi when using it in the studio). Other than that the machine is spot on – particularly so considering the age.”
“Roland Juno 106 for sale in good condition. I have owned this for 15 years, but It hasn’t been used in years. I have powered it on a few times over the years and let it warm up. It was also given a service about 4 years ago, everything was stripped and cleaned, but it hasn’t been used since.
“This is as close as you will find to a new SH101 very reluctant sale as I just don’t play it enough as I work away from home now. Home use only in smoke free studio.
“Very rare classic synth. Fully working, this keyboard comes in its original robust case which despite some wear and tear as well as some wonderful European touring stickers has kept this fabulous classic in splendid condition throughout its long life. My father reluctantly has given this to me to sell on his behalf as he no longer has use for it and is downsizing. His loss will very much be your gain. I have set the reserve at around half what this is actually worth so grab yourself a bargain. Happy bidding”
“Roland TR-808 Rhythm Composer In Excellent Condition
“Not much to say – pictures say it all. The synth is in near mint condition – it is 9.9/10. Silkscreen graphics are glossy and without blemishes, face is free of scratches or nicks. Minor scuffs on the underside from moving/racking this beast. All sliders and pots are mechanically nice and smooth, few are little scratchy – but it is a 30y+ old synth and as such sold “as is”. It looks as gorgeous and pristine as can be – and you’ll be very happy with its shape and sound. I don’t think you will find one in condition like this one any time soon… or EVER. That is, unless you happen to find a new one in the box.”
“Excellent Condition – Fully Functional”
“for auction is a used Roland JX-3P synthesizer. PLEASE READ FULL DESCRIPTION
“Up for sale is rare Korg X-911 vintage analog guitar synthesizer.
“This synthesizer is in good used condition, with some minor scuffs and scratches across the body. Power cable is hardwired. Pitch/Mod stick works as expected. Every key produces sound. Minimal testing of sound shaping functions though all seems to work. There may be issue of which we are unaware due to not being able to fully test this unit. Because of any unforeseen issues, being listed as Parts & Repair.”
“The MS2000R is, of course, the rackmount version of this beast. Although there is no keyboard and no real need for one, the 16 function buttons on the front of the unit can be switched into “Keyboard” mode in which they function as keys, mainly for demoing sounds while you’re programming it. This is a really great feature since most rackmount synths either don’t allow you to hear your progress from the actual unit or they only feature a one-note demo button to hear your sounds. The MS2000 is truly a well thought out instrument for musicians of any level looking for classic and new sounds within a quality digital synth with a sleek vintage look that’ll turn a few heads!” 
“For sale is one Korg MS2000 44-key analog modeling synthesizer. This is a digital synthesizer which was designed to emulate the sound, features, and control/modulation possibilities of a classic analog synth. As with many Korg products this synthesizer is very well built and includes a number of innovative features and surprisingly flexible routing (… and it sounds amazing!). It has been well cared for in my smoke-free home studio for many years. It has never been abused or gigged although I’m sure it would do fine if you were to bring it on the road.
“For the vintage keyboard nerd- I mean enthusiast. Lots of quirky sound-shaping knobs and buttons – throw some mild distortion and delay on it to make your tracks and live performance very unique.”

“All functions work. No sound through headphones (just noise). We have no ROM 3 cartridge to take it off “LOCAL MIDI”. Definitely needs ROM 3 cartridge. We believe that this keyboard will work just fine once the MIDI output is changed. Since we have no way of testing we are selling this AS IS and at a discounted price. All functions work fine. Again….NEEDS ROM 3 cartridge.”
