Just got my new Pro series Rex 4 string and it kicks major ass. I am amazed at how the EMG HZ's sound. I was totally ready to upgrade to DC35's like in the American series but I may just stick with what I have.
A fews years back I purchased a black legend 4 string off ebay. It was brand new. Shortly after that I replaced the emg ssd's that came in it to emg 35dc's. Its not the top of the line Spector but it plays and sounds great.
