Iconic BBC ribbon design, commercially manufactured under licence by Standard Telephone & Cables using spider technology.


Developed from the PGS, the 4038 was the BBC’s successful attempt at designing a general purpose pressure gradient microphone, with excellent linear performance at a reasonable size and cost compared to the AXBT.

Two versions were produced, a 30 Ohm version for outside broadcast and television studios, a 300 Ohm version for the sound studio.
