Groove Tubes is the brainchild of Aspen Pitman, a self-confessed tube gear addict. Over the years, the company built a range of distinctive tube microphones that have gained a reputation for their warm, flattering sound. This model has a new distinctive heavy punched grille inspired by early RCA mics, and a further layer of woven material made of nylon and copper forms an inner protective layer that also provides RF shielding.
 
This mic has a black satin nickel finish and red on the grill.

Because the 6TM is a tube mic, it requires one of the Groove Tubes’ external power supplies to provide the HT and heater voltages for the valve, with two channels, allowing two mics to be used from the same supply. The power supply connects to the mic via a multicore that carries both the audio signal and the power, but as a concession to the number of people who didn’t like toe 9-pin D-connector used on the earlier mics, the company has chosen to fit a 6-pin XLR connector to this mic. The mic signal emerges from the PSU on a conventional balanced XLR.
