I am repairing an Acoustic B200 Bass amp and had to take THE ENTIRE FRICKIN' AMP APART to change the Passive Input Jack! If the speaker wires were longer it not have been a problem at all. I have added 8" to the speaker and horn wires and I'm about to put it back together. Am I going to get a loud hum or some of horrible problem? I just find it hard to believe that the cost of a few inches of wire puts techs through such a long process when it could be so easy otherwise.
