It's not necessarily that there is a small voltage, it's that the only thing present on the cable is the "signal", as opposed to inside the unit where if you have an internal short you can have a real problem. There is typically only 9-12V inside the most units which is small voltage, yet they have high current and do cause damage when they short. Shorting "only" the line level signal it doesn't hurt anything. Equalizers work by shorting various frequencies from the signal to ground to remove them from the output.
If anything
does happen, then it's because there is already a serious problem within the amp.... In the same way that getting shocked while playing your guitar indicates a major problem. Otherwise it is perfectly safe.
But on the other hand, using a Y-adaptor could protect your equipment from faulty wiring inside the amp..... On the other-other hand, if the amp is faulty and the amp blows, then I don't think I would want to play it anymore anyways and risk getting electrocuted.
Better to toast the amp than yourself.
