Groove Tubes GT-44
Detachable-Capsule Pencil Tube Condenser Microphone
The GT-44 is a tube condenser in an end-address, “pencil microphone” form factor. Designed by Aspen Pittman, the mic uses interchangeable 3/4-inch capsules (available in Cardioid, Omni, and Hypercardioid patterns).
The capsules used a 19mm diaphragm made of 6-micron Mylar, vapor-coated with gold, within a 21mm (outside diameter) assembly.
Two switches on the body enabled an optional -15dB pad, or a high-pass filter (cutoff frequency 75Hz). These switches could be operated independently.
The mic’s body is nickel-plated brass.
The GT-44 included its PSM1 power supply and 25-foot cable, both a hard mount and a suspension mount, and a case for the microphone.
The mic was introduced at AES in the Fall of 2001, at an MSRP of $999. In 2004, the company was selling the mic direct for $599.
The Groove Tubes GT-44 is also known as: GT44.
The mic was released in 2001.
