Xpantastic!

sorry my first post is a FS post, but me and the Matrix did not get along as much as I thought we would. reply off list please. haven1 (at) gmail.com

am selling a Matrix-12 for $2700 USD (3 issues noted below)
Buyer pays shipping and packing from Vancouver Canada.
Verified Paypal only please.
Local pick up with cash OK.

- trades considered Nord Rack 3, Monomachine

I have some references on AH such as Intellijel - but I mostly sell
through Muffwiggler.com (the BEST modular synth forum) and the Doepfer yahoogroup 

- All voices pass the tuning procedure and sound similar
- 12 outputs are installed (possibly from the factory?)
- 2 fans are installed (possibly from the factory?)
- heat sinks are installed on the VCO chips (possibly from the factory?)
- made in Japan

Issues

#1 one button does not work (mod: tracking generator assign)
#2 one button needs a a bit of a rub (multimode)
#3 one encoder is mounted in reverse (clock wise turns decrease the
value) and has a different "click" feel to it (encoder #2).

#1 and #2 would probably be solved by cleaning the buttons. I don't
have time to do this so I have lowered my price. #3 is obviously a
repair job with the wrong part and polarity - polarity is probably a
simple wire swap - and not that good with an iron and it is cramped in
there.


more detail

encoder #2 has been changed by a previous owner. the feel of it is
different, meaning the clicks it makes are spaced wider - I think this
is called pulses per turn. The encoder output is also reversed, so a
clock wise turn decrease the value. I can tell the encoder is mounted
a different direction when looking at it with the matrix12 open as the
terminals are facing up, instead of down. unfortunately my camera will
not focus on this so I could not take a picture (I would need a macro
lens I think). this would make it easy to flip the terminal wiring I
assume. there was a post on the Xpantastic yahoo group a month ago or
so about where to source replacement encoders that will work.

the tracking generator assign button in the mod routings row does not
work. It probably just needs to be cleaned. some other buttons need to
be cleaned as you need to gently rock the button for it to work. The
tracking generator assign button is the only one that does not work at
all, the rest are a gentle rub and it works. this happens to all the
gear with this kind of button and apparently and it is a an easy fix
by taking the buttons apart and cleaning them with. These buttons are
hard to replace as the manufacturer will only sell them in large
amounts, so I decided I could live with one button I never use not
working and did not want to risk taking the whole machine apart. The
button is the same as in the Eventide H3000 if that helps. There is
lots of info online about this as everyone with an Xpander or
Matrix-12 has had trouble with the buttons it seems.

These issues and the cosmetic scratches you can see in the pictures I
feel devalue the Matrix-12 I have, hence my lower price than normal.
If I brought it to the local techs I could get it fixed up %100, but
the labour costs would mean I would have to raise the price, making it
harder to sell. If you are DIY inclined you stand to save money if you
decide to make these repairs. I have been using it
without making the repairs as I personally find them to not prevent me
from using it in music.
