It's probably a "ground loop" hum and most likely caused by the Korg Tuner.
Isolate the Korg from the Mounting rails in the rack and that will probably do it. |

FWIW. Furman has some new solutions to the ground loop problem. Many of the rack rider units have "LIFT" technology.
These things work. I run two 100 watt tube amps, and an efx-processor. Hum is gone. No grounds lifted.
hope this helps

| I think Jack hit the nail on the head. I have two Korg tuners which I isolated by using a 3-prong to 2-prong AC adapter. Also try moving the interconnecting cables and listen for changes in the hum level. |

| The Tubefex is also grounded and will cause hum, as it is grounded via the signal cable to the amp and to earth via the 3-prong plug. Use a Hum-X by Ebtech to safely eliminate the hum while keeping the Tubefex properly grounded. |
