Hello,
ch #1 is silent, 2 & 3 have a hum all the time. If I plug straight into the front of the amp, no hum. Didn't have the hum before the RG. Same pedals and power. I can unplug the power supplies, still a hum. I can disconnect the fx loop, still a hum.
If I unplug the ch. switch cable from the RG the hum is a little less, but still noticeable, maybe 40% less.
If I leave everything the same and simply take out the cable to the front of the amp and replace with straight from the guitar it's gone. Ch. 2 or 3 still on, RG on etc. Simply change to direct from guitar.
Would this be considered ground loop hum from the RG? If I perform the ground lift internally (with Ron's guidance) will it matter afterward if it's not the solution?
Thanks very much
