I heard today that PRS will no longer be referring to the MDT as the MDT. It will now be "Paul's Custom Amp" and MDT won't appear anywhere on the new ones. Apparently, another amp company objected to the use of the term "MDT" and so PRS changed the name.
Not sure of the accuracy of what I was told, but I do see the PRS website now lists it as Paul's Custom Amp and there is no mention of MDT in the description. Is this old news or something new?
