I’ve just picked up a 2880 looper and there is an intermittent rhythmic hum being emitted. It’s in time with the tempo, but it’s not the click track and the tempo volume is turned all the way down. It sounds regardless of wether you’re recording or not.
Evidently I was using a power supply without a high enough power output. The BBE is only 200ma, and once I changed to a power supply of 500ma the noise was gone. Posting this for any future users who may have this problem.
