This is an early, valuable shielded cable type T. There is a slight difference in sound compared to current products because the impedance of the circuit differs between the shielded cable and the 4-con type. The shielded cable type has a slightly gentler presence, but has a higher density in the high frequencies. I have also used the 4-con type, but I preferred this one because I felt more power in terms of listening. The sound image is like a natural saturation of Seymour Duncan's Nazgul and Sentient. The gain is lower with the DH250, but I felt the band characteristics were very similar. It was working without any problems until just before removal, but please note that there is no operational guarantee due to the nature of the product. I have sold several pickups so far, and there have been no reports of problems so far. No price reduction or questions will be accepted.
