Vanguard Audio Labs Custom Shop now offering Custom Laser Engraving! 

With our new laser engraver, you can add customizations to any of your Vanguard microphones...Studio logos, an inspirational quote, sharks with frickin’ laser beams on their heads…we can do pretty much anything!

When you purchase this, our team will reach out to you to finalize your design. You’ll receive a proof of the design from our team and we will need your final approval before we run the engraving process.

By purchasing, you acknowledge a few considerations - 

The rear of the V13 is vented for the tube, so the available engraving space will be necessarily smaller

If purchasing this for a previously-purchased microphone, please note that you will need to ship your microphone body in at your own cost and pay for return shipping.

Gen1 mics utilize a C330 brass material, whereas gen2 mics we are using SUS304 stainless steel material. The look on a gen1 mic will be very different than a gen2.

For logo's or other images, you must upload an exact file of what you would like to create the design. Derek sucks at graphic design, you wouldn't like it anyways.

Due to the customizable one-of-a-kind nature of this process, please note that this makes your purchase non-refundable.

Once the design has written approval, it is set in stone. Requesting any further changes after final approval would warrant an additional engraving charge.

*COSMETIC B-STOCK – FULL WARRANTY AND FULL FUNCTION GUARANTEED.* We are very picky with our standards, so anything with minor defects/ mistakes in painting or laser engraving and gets rejected. Occasionally we will build out a microphone specifically from this “cosmetic reject” stock and offer it at a discount. For the Eclipse mics this will almost always be a very minor laser engraving error.

When you buy a V4, you also get a VLSM Heavy-Duty Shockmount. We wanted to rethink the standard “spider-style” shockmount of old, and designed the VLSM with a few nifty features. First is the open front, which allows you to position the microphone as close to the source as necessary. Second, we install aerospace-grade suspension rings that won’t break, sag, crack, or stretch over time. This shockmount was designed to fit any microphone with M22x1 threading, so you also can use it with a number of microphones from other manufacturers.

When not in use, your V4 should be stored in its padded pinewood box with the included dessicant packet.
