BAS-1: What can I do when the jacks on the rear panel of my amp (such as the AC IN) are blocked by the rear pipe, and I can’t connect the cables?

The position of the rear pipe may block access to the jacks on the rear panel of your amp, depending on the angle that the amp is set up.

Try adjusting the stand so that the jacks and the position of rear pipe do not interfere with each other, within the range indicated by the markings on the cam.
