This Sequential Pro One is a marvelous synth in good condition just back from service performed by Sam Masuko of Three Wave Music.  Those of you who know Sam know his rich history as an engineer and know that the work he does is top shelf.

AND the synth wasn't shipped there.  I put it in my car, drove it there and picked it up myself when it was finished....because I hate what shipping can do to vintage instruments.

SO!  It fully works and it is a beautiful beast.  All the functions operate correctly and all the keys play.  There are some minor physical blemishes consistent with the age of this synth.

- see the "DEFECTS" picture detailing three imperfections
  1. two circular cracks on the lower right faceplate (not super noticeable)
  2. a slight waviness on the "Sequential Circuits" name tag under the keys (it is slight, but I am picky and telling you)(about the imperfection, not that I am picky)
  3. Damage to the right rear endbell.  I have to be honest here, the endbells were not exactly made of fine hardwood and I was thinking of replacing them with something more attractive or trendy if I kept this board, which I may still do because it really is a unique piece).  They are simple to replace -- two (2) external screws and you are there.


If you are familiar with the Pro One, you know that its heritage was from the famous Prophet 5.
