Has anyone ever tried out these pedals on bass? I know that the ds-1, mt-2, and the sd-1 are the boss distortion pedals commonly used on bass, but has anyone tried the md-2? the boss website has only one sound sample of the md-2 on bass and it does seem to have a nice grinding sound on bass. other than that, has anyone here experienced the boss md-2 mega distortion on bass?
