I have an op-33 it stopped working
I have an op-33 it stopped working I contacted teenage engineering and they advised that it s because I was using rechargeable batteries From what I remember I couldn t see anywhere in the instructions where its stated that I couldn t use them again from what I remember I think I explained this to customer service Either way teenage engineering sent me out a new unit free of cost and told me I could keep the old one for spares What more could you ask for I can t remember the exact date this happened but it was a while back
