Boxed 1960s 600 Ohms Chrome Grampian GR1/M Ribbon Microphone

This is a Boxed 1960s 600 Ohms Chrome Grampian GR1/M Ribbon Microphone. A 600 Ohms impedance semi-cardioid ribbon microphone in a satin chrome finish. Made in the 1960s by Grampian Reproducers Ltd, of Hanworth Trading Estate, Feltham, Middlesex, England. Sought after and extremely difficult to find, especially in unused condition, and we have two available! The price quoted is for one microphone.

Both microphones nestle in a black leather padded instrument case within an external blue cardboard box, and are accompanied by an instruction leaflet and sales leaflet. They were sold from new without a lead, swivel holder or switch assembly. They have not been tested, and will probably need some work after 50 years of storage: the foam interior is likely to have disintegrated. But they can’t fail to provide a bit of vintage glamour and music history for your recording studio, shack or lounge!

In ‘as new’ cosmetic condition, except for the external blue cardboard boxes which have some scuffs and storage damage. The internal instrument case is in excellent cosmetic condition.

The microphones are labelled GR (Grampian Ribbon), followed by 1 and M. The GR1 designation was used for the semi-cardioid version, and the GR2 for the standard figure-8 pattern. The GR1 has a silver grill at the front and a black oxidised grill at the rear to show its asymmetry, whereas the GR2 has two silver grills. The letter ‘M’ designates the impedance of 600 ohms. Medium impedance models were used with, for example, transistor amplifiers and tape recorders.

The GR1/M was sold for high quality reproduction of sound and recording work. Grampian advised that this type of microphone should not be used for ‘close talking work’ nor should you ‘blow into the microphone.’
