Bought used (8500F!) In the 80's, I love it! it is true that four tracks is a bit light, but my models enough for me: I play live (piano) sequencer with recording in stereo on tracks 1 and 3 I still have 2 and 4 for singing and the guitar! The party table mix is ​​excellent, no breath, materials of very high quality, robust. The K7 is also part of very high quality despite the frequent blocking of the trap of K7.Le dbx Pro is really great (no breath).
Quality / price ratio excellent today saw its low rating on occasion (the 300th). At that price you'll put a dozen Hsiu ... please!
