Howdy! Love my B9! I’m in love with all of the 9 series and will probably end up with a board full of them! I have my rig set up using a Morley switcher. I can switch between electric, which sends my signal to my amp, acoustic, which sends my signal directly to the board, and organ, which sends the signal through the B9 and then to the board. My B9 has produced a hum from day one. It’s a high-pitched cycle hum and is audible through all channels but especially through my amp (Vox ac15cc). This hum is audible even when the pedal is shut off. The only way to get rid of it is to disengage the power jack. I have removed the pedal from the effects chain and plugged it directly into the amp and still get the hum. It’s loud enough to be unacceptable. I’ve gotten into the habit of reaching down and unplugging it when I’m not using it. This too is unacceptable. I would throw it into the stompbox graveyard but this thing is indispensable to me! As the Mel9 shortly will be as well!

Somebody help me!
