From Our Research Team:

Tube-powered Workhorse

The Groove Tubes GT40 is a medium-diaphragm condenser that's great for a number of recording applications. From acoustic guitar to drums to small vocal or instrumental ensembles, the GT40 captures it all in great detail while imparting the sweet Groove Tubes tone that has established them one of the leading authorities in tube-based technology. A true condenser, the GT40 sports a .75-inch medium sized capsule with a thin 6-micron Gold evaporated diaphragm in a top firing design. A Groove Tubes GT6205 tube powers the electronics in a Class A Design. Included in the system is a PSM1 power supply, multi-pin 25-foot soft audio cable, hard mount, AC power cable and mic case.

No one knows tubes like Groove Tubes and the GT40 is a prime example of that. The legendary GT low noise GT6205M tube in a Class A triode circuit design provides warmth with detail, adding new dimension to vocal and especially instrument recording. Custom-wound nickel core output transformer gives complete isolation and low distortion. The hand-selected low noise USA-made vacuum tube is powered by the auto load-compensating PSM Power Supply for extended cable runs.

Reviews

One of the best all-purpose tube mics

by Darnstrat from Terre Haute, IN
February 24, 2009
Music Background: recording engineer, producer.
I've been using a GT40 in the studio for a couple of years now. So far, the only instrument that it hasn't been perfectly suited for is a close-mic'd violin. From a distance (2 meters) it's fine.... read more [+] />
Vocals shine with this mic as do acoustic guitars.. a bit of top end brightness without being shrill. A nice gloss. Very solid and tight low end, perfect for acoustic or electric bass.
As I said earlier, the only thing where it wasn't perfect without some eq was on violin.. and with a high-end roll-off, it would work nicely.
It's incredibly well-built, has a great shock mount, and the cabling and power supply are heavy duty. Built to last and built to sound great. close [-]

Sweetwater Advice

Andrew Malloy
This is one of the few mics that can make my finicky guitar speak up. The tube richness adds a complexity to the low end and just seems like pure magic for the highs. The GT40 is the mic that can make your acoustic sound like you've always wanted to hear it.

Our Customers Say...

When it came time to start from scratch with the studio, I had a lot of questions. The Sales Engineers I've worked with are really friendly and patient, and the guidance they provided was invaluable; they basically helped build the studio.
