"CR-8000s are seriously lovely drum machines, but they have tended to last less well over the years than some of the other classic Roland drum machines. This one is an exception. It looks like it could have been made yesterday. Why have we not called it mint? Well, if you study the close-up pic of the left front corner, you might see some tiny marks. But this still exudes an amazing quality of newness.

In full working order (obviously scarcely played at all in its life) with its original user manual and service manual, and with its original carton and internal polystyrene bits. It also has its original dust cover, which possibly helps explain how incredibly new it looks. We'll cover the carton in card to keep it free of address labels etc..: 6GBP."

"This is a professionally built Formant Pro latest version. It has a Midi CV keyboard that plays really well. It is in superb visual condition. There may be the odd crackle or contact problem in a knob or jack but it is in principle fully working. the reverb need to be attached to a reverb tank. its a massive system with a sound to match. I had a few homemade models as well. this is miles apart in terms of quality."

"One of the classic analogue modular (OK semi-modular) synths. It's actually not perfect condition on cosmetics, as you can see in the photos. There are some scratches on the sides and back - though the important bit (the front panel) is in very good condition indeed. But the sound is excellent as expected, beefy and powerful, and really such a good semi-modular with complete Eurorack and MIDI compatibility. Switchable voltage - supply your own IEC lead for price, ease and safety of shipping."

"Very very rare and in very nice visual condition. By one of the greatest manufacturers of synthesisers. Can be played via an interface cable ending in 3,5 jacks for CV/Gate etc. (included). I used my Roland 184 (not included) because the 3000 wants to see a healthy voltage. I went through the main functions (oscs, filters, adsrs) made a few patches and everything seems to work well. However a good number of the potentiometers need cleaning and/or more usage. Expect to put in some standard maintenance work to make it perfect. The filters can easily be overdriven resulting in an aggressive sound."

"One of the classic modules of all time, and in its original R.A. Moog incarnation, dating from January (or possibly November) 1969. This example has a 'Bypass' switch mod. This looks very much like a factory modification requested by the original buyer - the style of switch and the black Dymo label seem exactly what Moog would have used at the time. Bought by the current owner in 1999, with light use in a smoke-free home studio. Working well. At some time in the past this actual module was sent to Paul Schreiber to help him design the MOTM 940, and Paul calibrated it to self-oscillate correctly. Situated in the USA but light enough to send economically worldwide."

"Four classic mid-seventies modules: one 921A Oscillator Driver, and three 921B Oscillators. Complete with an International Power switchable power supply (now more commonly badged Power One) and a wiring harness / loom wired for five modules - the four 921s here, and a fifth module - until now, the 904 in the previous lot. ***This will need encasing***, and of course the modules will need to go in a simple case or an existing cabinet. In very nice cosmetic condition, and working well. Bought by the current owner in 2003, and since lightly used in a non-smoking home studio. The power supply has a standard IEC mains socket and fused switch with power light. The fuse will need to be changed if the voltage is switched from USA, where it is currently located."

"One of the rarest synths ever - this one is serial number 7 out of about 10 that were built. They were designed in the late 70s by Steven Waldeck, professor at the Art Institute of Chicago. Although there are so few of them there is a good deal of information gathered at the excellent matrixsynth site: https://www.matrixsynth.com/2016/05/more-info-on-vintage-waldeck.html?m=1 We had this example imported from the USA with the aim of having Dani at Hideaway do her magic - but sadly she has too many other projects on the go, and could give no idea of how many hours it would take - and how economically viable it would be. She did check it for electrical safety: 'If it was a 240V piece I'd say it would need some serious attention to detail and most definitely grounded - at 120V, I would say at the very least it should be checked over properly and some addition of sleeving/insulating sheet of the mains wiring on the transformer, fuse and switch terminals.' Bear that in mind along with Mark Verbos' honest appraisal of another example from the matrixsynth page, and consider it a fascinating project, inspired by the VCS3 but definitely not a VCS3. Good for sound effects and weirdness, but not accurately pitched notes. Dani's general verdict as it stands: 'This was clearly intended to be aimed more at making sound effects than to be used as a well calibrated and stable musical instrument - the whole thing is extremely drifty with very narrow usable control ranges on the oscillators - there is a fair amount that doesn't work but I still had some fun making some sort of recording with it to mark the occasion.' https://soundcloud.com/hideaway-studio/1978-waldeck-on-the-waldeck/s-2j3HAUd60BE (corrected URL!)"
