I have received a BE100 Deluxe and straight out of the box the HBE channel it's pretty much unusuable because it has this really unpleasant high pitched whistle all the time. The more you turn the volume up, the more unbearable it gets.
Only when I hit the strings the whistle stops, but otherwise it's all the time there.
