I have an Sd2 as part of my rig. It is my second- sold first one should have kept it. I had an SD3- sold it should have kept it. I had an SD4- sold it should have kept it-LOOKING for another.. I almost got an SD5- should've bought it and kept it.
Have these become extinct, or are others wiser than me clinging to theirs? I can't find a used or demoed SD4 anywhere..

Whilst it is very unusual for Ketron to remove a product completely, the SD4 is no more sadly. I believe remanufacturing would have been too expensive. Its a pity as it was an amazing little module that was not appreciated enough.
Used Solton and Ketron instruments are hard to find, most musicians keep them as back ups, or just because they have invested so much time in customising the way it operates they just dont like getting rid of them. Most Ketron owners I know still have all their previous models too!
