I have always experienced a very unpleasant HUMMMMM when plugging in ukuleles into my small amps - the Roland Microcube and the VOX Mini.
For years I thought this must be due to some sort of electrical mismatch between piezo pickups and amps suited for electric guitar.
But I noticed that my Gibson Les Paul Electric guitar with humbuckers would also hum on my VOX Mini amp specifically, but not on any of my other amps. I initially thought it was because there was something wrong with my guitar, but when I took it to the guitar technician who opened it up and inspected all the wirings, it came back with nothing diagnosed...
Last night, I decided to try an experiment and used a different power supply plug on my VOX for the first time..
AND VOILA! NOISELESS AMPLIFICATION.
On both my guitar AND all my ukuleles!
I feel kinda angry that VOX would provide power supplies that would cause prominent EMI hum...
But I feel greatly relieved that a dilemma I've been having for years is solved.
If you get nasty hum on your amplifier, try changing the power supply!
