COLES 4038 vs OPR ROCKET 4038 Plugin Presets/Expansions
Old 5th March 2019
COLES 4038 vs OPR ROCKET 4038

This is a comparison of the Coles 4038 and our new O.P.R Rocket 4038 which as far as I'm aware is the first and only ribbon mic with a 0.6 micron with a motor design inspired by the Classic Coles ribbon ribbon mic.

Also available as a mod for long geometry budget ribbon mics more info here


The OPR Rocket 4038 is more than a "mod." The ribbon motor assembly and transformer are designed and manufactured from from the ground up in Melbourne Australia.

Torroidal transformer hand made in house here in Australia.

0.6 micron with a motor design inspired by the Classic Coles ribbon ribbon mic.
