"A super musical Italian combo (strings, polysynth, monosynth) with aftertouch and preset editing capabilities. Visually, see photo, it works, but it's not a museum piece.

Technically 95% OK (some potentiometers crackle a little, strings 4' in one octave don't play, the same for strings 8' in another octave), which is still a great result for Soundmaker (about 7 years ago, a general overhaul was carried out - most CMOS and electrolytic capacitors were replaced + calibration).

Sound sample from this particular piece: http://mp3.bodyia.cz/Soundmaker.mp3

Personal pickup possible in Prague (CZ) or Essen (DE)."

Click the auction link on top when you get there for additional listings.

"A superb Roland HS-60 (aka Synth Plus 60) which is essentially a Juno-106 with speakers, in near-mint cosmetic condition. Fully functioning - do please note, if you're not familiar with these, the bass sounds can become quite distorted when played at high volume through the internal speakers - so use your studio monitors or headphones instead! Complete with printed / bound owner's manual as well as original Roland promo leaflet.

This will be brought to VEMIA for expert packing: 24GBP."
