Do I need a DI box?

[Number6]

I'm getting one of these next week:

Litejam Smart Guitar with a Full-Spectrum RGB Fretboard

See what you're playing. Learn faster. Perform with confidence

litejam.com

It's a bit of a gimmick but hey ho.
Now this guitar has LEDs and I've heard horror stories that these LEDs make the output noisy. Not only that I live next to a railway track that gives bad EMF.

I have a Quantum 2626, of course the guitar goes into the first couple of inputs (I'll use virtual amps). My question is will buying a DI box help me keep noise lower or is it strictly unnecessary?

Are there any magic boxes that I can put in that will help? Recommendations?

I do have Beringer HD400 hum eliminators which work well with noisy USB instruments, it also stops RF noise from the 2626's output to my Yamaha monitors. No use for guitars though I would assume.

Thanks.

If the LEDs are built into the guitar and cause noise on the guitar's output signal, you won't be able to remove this noise with a DI box. DI boxes are not designed to remove noise that's already part of the signal.

But I think the guitar's circuitry design isn't that bad. The LEDs most likely won't produce any noise, so this will not be a problem. What can cause noise are connections between mains-powered, grounded devices such as a guitar amplifier connected to an audio interface or mains-powered stomp boxes connected to a guitar amplifier. At least for the connection between a guitar amplifier and an audio interface a DI box could be useful. But be careful with the type of DI box you pick: to connect a line level output to a line level input, you'll need a device like this one. To connect a line level output to a balanced microphone input, you'll need a device like this one.

As stated I'm just plugging in the guitar directly into one of the first two sockets of the 2626 which handle pretty much everything, and I've already got a couple of HD400's for instruments powered by USB and monitors (does an excellent job).

So I guess I don't need a DI box and I'm good to go. Thanks for clarification.

If anybody has any other ideas I guess to deal with RF please let me know.
