Thanks to companies like Line 6, amp modeling technology has expanded into other gear, including wireless guitar systems.

Case in point is the Relay G75 with its Cable Tone Technology, which adds back the subtle high-frequency roll-off effect that real guitar cables add to the overall tone.

But it’s not just about cable modeling because it is well received for its tour ready hardware, modern 2.4GHz operation, and battery saving feature.

Speaking of batteries, the transmitter runs on regular or rechargeable two AA batteries, which gives you over 8 hours of use, standby time is extended by the transmitter’s smart power saving feature.

Ironically, there aren’t many who report on Line 6’s Cable Tone Technology, but there are no negative reports either so it’s not much of a big deal. However, there are some who feel that the transmitter eats up batteries too quickly, they recommend investing on good rechargeable batteries for convenience and for long term savings.


Whether you’re into Cable Tone Modeling or not, the Line 6 Relay G75’s reliability and sound quality is well worth the investment.
