Hey guys, Apologies if this is a no-brainer - leads don't seem to be sitting in my bass' input jack securely. The input seems to be working fine but if the lead gets pulled on and moves slightly (while still in the input) the amp loses signal or it becomes filled with hiss. It seems to vary from lead to lead as well (the leads are cool - I've checked them with other instruments). Any suggestions on how I can fix this problem? Any help is greatly appreciated. Cheers.
