2 previous owners (incl. me). Light home-studio use in smoke free environments.

Premium electronics upgrade carried out by Michael Joly at OktavaMod (certificates included).


The Premium Electronics package extends bass response and moves the HP corner frequency down over two octaves so the phase shift in the audible bass region is eliminated - much punchier bass in other words. The PE mod also reduces noise by upgrading the FET to a type that has a noise spectrum curve that actually declines in amplitude in the critical 2-4kHz band relative to 500 Hz. The FET is individually biased for lowest distortion / maximum headroom. The upgraded FET also offers faster transient response by reducing capacitive loading of the capsule. Finally, the PE mod reduces grittiness to produce a sweeter top end.
