Issei Noro

In the YouTube video “T-SQUARE 35th Anniversary Festival disc 1”, Issei Noro is observed using an Ex-Pro Pro-10z Wireless Instrument Receiver as part of his live rack setup. At approximately 1:05:18, a close-up of Noro’s rack reveals a unit that matches the Ex-Pro Pro-10z Wireless Receiver by its 1U rack format, centered Ex-Pro logo, dark front panel, antenna layout, and LED indicator section. This setup is consistently part of Noro's live guitar configuration throughout the concert. The video is credited to Jerry's Funk and Fusion Collection.

In the YouTube video “Casiopea 3rd - A･So･Bo Tour 2015 (カシオペア・サード)”, uploaded by T grace, Issei Noro can be seen using a Line 6 Relay G90 Rackmount Wireless System as part of his live guitar rig.

At approximately 16:58 into the video, the camera briefly shows Noro’s rack setup on stage. The upper rack unit can be identified as a Line 6 Relay G90 by its characteristic pair of front-mounted diversity antennas, dual RF signal meters on the left side of the front panel, central blue backlit display, rackmount format, and overall front-panel layout unique to the Relay G90 wireless receiver.

The Relay G90 appears to serve as the wireless front end of Noro’s touring rig, receiving the guitar signal before it is routed to the rest of his rack-based processing system.

In the Yamaha Backstage article “HELIX導入でギターサウンドが激変!? 野呂一生の最新システム” (published on Yamaha Art Blog in April 2018), Issei Noro's live guitar rig is shown featuring a Line 6 Relay G70 Wireless System.

The article documents Noro's transition to a modern Line 6-based setup centered around the Helix platform. The Relay G70 can be seen as part of the signal chain, serving as the wireless front end for his guitar system. Its distinctive floor-based receiver/transmitter architecture, display layout, and integration with the Helix-era rig identify it as the Relay G70.
