Just made this and it works as a great hum pot adjustment tool! I used the Switchcraft 1/4" adapter.
I plugged into my Stereomour and thought hmmm....hums a bit - needs shielding. Then realized that the hum pots were probably off. Small adjustments on the hum pots as I listened with volume at 0 and dialed them right in. Hum gone.
Very nice!
I was worried about the wires breaking off at the banana's. That's pretty small wire held down with a screw. As strain relief I just filled in the holes with hot glue. I know this makes it a one-off but for the cost of the banana's - not an issue.
