Digital wireless guitar systems.

It is natural for guitar systems to join most other wireless technologies and go digital.

Only now that a few good years have passed can we properly evaluate them. But how do they work? For analog systems, the transmitter converts the sound of the guitar into VHF or UHF radio waves.

But in the process of converting to VHF or UHF, something called a compander is used to squash the signal to fit in the VHF or UHF range and then when it hits the receiver, it expands back to the original guitar sound. But inevitably when you squash the signal in this way, some quality is lost.

With a digital system there is no compander, so there is no squashing of the signal and therefore it sounds much better; the signal should come in exactly the same way it came from the guitar pickups. Another problem with VHF or UHF systems is bandwidth and, in particular, bass noise.

The bottom E on a bass is 44Hz and some VHF or UHF systems just don't get this quality range, something similar can be said for higher sounds; some quality will be lost. However, a digital system will have the full range and minimal sound quality will be lost. With a digital system you shouldn't receive any interference, certainly not from anything on the VHF or UHF frequencies like radio waves and TV signals.

Other digital signals like phones, Bluetooth, and wireless internet should not be picked up by a wireless guitar system because the receiver is only looking for a digital transmission from the transmitter, which is encoded in a certain way.

All other digital transmissions are ignored, making the possibility of interference practically impossible. The weak point of digital transmission used to be the range, but thanks to technological advances, this is no longer the case.

You can see from the Line6 Relay range of digital products that they have increased range substantially with each new model, the G30 has a range of 30m, the G50 has a range of 60m, and the G90 has a range of 90m.

So in general, you have to say that digital systems seem to be superior to VHF or UHF systems, before it was difficult to justify the huge amounts of money you would have to spend on a digital system, but now they have come down a lot in price; You can even buy the Joyo digital system for £ 87.99 (about $ 145)! So the best quality, reliability, and now the same range make digital systems a great buy. But still a lot depends on the quality of the build.

A high-priced UHF system will almost certainly be better than a low-priced digital system. But the best general systems will be digital ones.
