9V Battery Hiss?
Posted: 19 Apr 2021 12:36 pm
Today I received a Goodrich Baby Bloomer effects pedal and installed it at the end of the effects chain as advised. The device produces an astonishingly open tone that is also clean, clear and (depending on the settings) bright and razor-sharp. Absolutely wonderful. Highly recommended.
I did, however, detect a soft, high-pitched background hiss. Turning down the treble on my Kanata 50 suppresses the hiss to some degree, but with an unwanted loss of treble tone, of course.
I use a TrueTone 9V power supply, but when that line power is shut off, the internal 9V battery keeps the unit powered on until the on-off button on the BB is pressed. When I removed the battery (and used only the line power), the hiss vanished! Can someone explain this phenomenon? Is it a common occurrence?
