Effects pedals help

[gothpugs]

As above, can you use any pedal or are their specific distortion pedals etc. For basses

[bobbass4k]

You can use any pedal with any instrument (or anything you canplug into it for that matter). Whether it sounds good is a different matter. Most guitar distortions will cut the low end out of your signal, there are some that are really good with bass though. You can get a bass specific distortion, or you can get a blend pedal to blend your natural bass sound with a pedal. That way you can use guitar distortion and still retain the low end.

Yes you can.
In fact pretty much all off my pedals are not bass specific.
