Can I use both a mono or a stereo input jack for a bass amplifier? What is the difference between the two? I broke the input jack on mine and can't decide what to replace it with.

Also, are input jacks universal as long as they have 6 pins and and the input side fits through the hole on the front panel of the amp?
