Sequential Circuits Prophet-5 Anvil Road Case For Sale. This foam originally inside this sturdy road case deteriorated, as vintage foam usually does. The previous owner replaced the top and bottom foam pieces and wedged some smaller pieces in between the sides and front and back of his Prophet-5. This worked well enough to ship his P5 safely, though we recommend you do a better job at refoaming this case before using it. This unit will ship as shown. USA sales only.
