Someone on the AH list is asking about how to remove the matte finish from an Xpander and while I found some photos I can't seem to find the info on how to do it. I vaguely remember that it's not all that difficult but I can't find any instructions. Anyone know where it is?
Gloss finish Matrix 12, for reference: https://www.matrixsynth.com/2016/09/vintage-analog-oberheim-matrix-12-with.html
Thanks,
