GT-67

The GT-67 uses the same capsule as the GT-57, but amplifies signal with the help of a miniature Pentode instead of a Field Effect Transistor. Like all of the GT microphones, the 67 is transformer coupled. The 67 has a number of selectable polar patterns which makes it an extremely versatile microphone. On the back of the 67 you will find Cardioid, Super-Cardioid, Bi-directional (figure 8) and Omni. Switching polar patterns also changes the frequency response of the mic, and this gives a number of different timbral options while recording. You will also find a (–10dB) pad switch and a 75Hz roll off filter on the front of the mic.

The 67 comes in a “flip-top” box with a rather heavy power supply, a nice shockmount and a multi-pin XLR cable that connects to the power supply. Tube mics require their own power supply since tubes due top the need for more than 48 volts to power the plate. Condenser mics also need power that is dedicated to power the diaphragm.

I mainly used the 67 to record male vocals and clean to moderately distorted guitar amps. On male vocals, I fell in love with this mic and ended up using it a number of times. With this vocalist, the 67 actually beat out a number of other well-known microphones. This mic maintains amazing detail throughout its frequency response yet had enough highs to cut through dense mixes, without sounding harsh or muddy in the low-mids as is common in many large diaphragm tube mics. I also got great results with the 67 on a Vox AC30. It gave a lot more detail than the dynamic mics we tried and also captured small amounts of the room we recording in. Capturing the room, in this case, gave the guitar a more natural sound than you normally get by placing a microphone 2” away from the speaker. The 67 also had great detail while recording a mono drum overhead and a drum room.

The 67 is a great microphone for male vocals and I would not hesitate to use it with any female vocalists. When matched with a good pre-amp the 67 shines. Returning this microphone to M Audio was a rather painful experience. I am planning on picking one up for my next recording session!
