Vintage vocal microphone

The GM 55, from Thomann's in-house brand the t.bone, is a dynamic microphone that stands out with its distinctive retro look and sound, drawing inspiration from a classic 1939 model famously associated with Rock & Roll legend Elvis Presley. Delivering a characteristically warm and balanced vintage tone, the GM 55 is also remarkably resistant to feedback, making this microphone an excellent choice for Rock & Roll singers who move around the stage and want to infuse their performance with a touch of nostalgic charm.

Nostalgic sound and look

The GM 55 features a moving coil capsule with a frequency range of 40Hz to 17kHz, closely replicating the sound of its classic inspiration, while the housing design with boosts at 5.5, 7, and 10kHz enhances its vintage character. Its supercardioid polar pattern reduces sound from behind and minimises side noise, allowing for clear sound capture, and with a field transmission factor of 2.4 mV/Pa, the GM 55 produces a strong output that can clearly pick up even quieter voices on stage. A swivel joint connects the capsule to the neck for easy alignment with the vocalist, and the on/off switch sits on the neck, while the base houses a 5/8" stand mount and XLR socket for seamless integration.

The t.bone vocal microphone with table stand

All eyes on the vocals

The GM 55's striking appearance instantly draws attention to the vocalist, with its polished chrome-finished metal housing – crafted from two screwed-together parts – making this microphone a real eye-catcher on stage. Combined with its low susceptibility to feedback, thanks to the supercardioid polar pattern, the GM 55 is well-suited for high-volume performances, particularly in loud Rock & Roll bands where vocals take centre stage. On top of that, the GM 55 offers impressive value for money, standing out as an affordable option compared to similar models.

About the t.bone

Since 1994, the t.bone has been one of Thomann's in-house brands, and its name can be found on devices such as headphones, wireless systems, in-ear equipment, and various microphones and matching accessories. "the t.bone" products are made exclusively by renowned companies who also manufacture products for other well-known brands. This provides a clear advantage: Brand-quality products at very reasonable prices. And word gets around: One in seven Thomann customers has already bought at least one product from the t.bone.

Includes table stand and case

True to the style of classic Elvis microphones, the GM 55 exhibits a dip below 1kHz, while the proximity effect – triggered when singing close to the mic – naturally enhances the bass response. With a relatively high impedance of 415 ohms, the microphone pairs best with a high-impedance microphone preamp. For streaming or podcasting, the included metal tripod table stand offers a convenient desktop setup, and a 3/8" thread adapter ensures compatibility. To top it off, the supplied plastic case allows for easy and secure transport of both the GM 55 and the stand to any performance venue.

Looks great and it's a bargain.

Halley 18.06.2018

This mic has distinct look, and stands out from the box standard cones. It's quite heavy, so it won't break easily. Beside the look, it sounds great as most other mics from the t.bone family (we currently use the MB85 beta, DC1500(drum kit) with pencil mics(EM700) and MB75(which I prefer a lot more than the SM57 on snare and guitar mic). They all have been gigged a lot, and still sound as good as new.

As with any other mic, you will apply some EQ to suit your voice better, so the t.bone sound as good as a much more expensive Shure on live applications.
If you are recording, you should be using condenser, so I'm not mentioning studio application.

Con: As the only way to attach to the stand is by screwing(just like the shure) you can't get it out as you please. If you like to walk around with the mic, just know that you can't put it on the stand, or you have 2 mics (or a wireless one)

Great value for the money

I bought two of these, one for me and one for my bands bassist. We play rockabilly (and some punk rock) and the design is spot on for that style. Our singer use a similar (nearly identical) microphone of a different brand but I'd say it is nearly impossible to tell that apart from this based only on the sound. Neither me or my bassist have had any quality problems and we have played probably about 30-50 gigs with these microphones, packing and unpacking between gigs. My recommendation is that unless you really want to buy a more pricey microphone, for whatever reason, this is a great choice.

Looks great. Well made and robust. Still looks good after many gigs. Acceptable sound for the price.

10 years old and still going strong!

I bought my t.bone GM 55 in April 2008 and have gigged with it hundreds of times since then. It's still going strong! I bought it because I wanted a vintage style mic, but couldn't afford a Shure S55. It's well built, looks the part and sounds good.

It may be a third of the Shure's price, but it certainly isn't a third of the microphone. In a direct comparison you'd hear the difference, but in a noisy gig environment you'd be hard pressed to really notice.
