Help! Emergency!!!

[Eric Garcia]

So last night I show up 2 rehearsal with my BSRMW6, go to plug in and all of a sudden I have EXTREMELY LOW OUTPUT VOLUME, 1st thing I do is swap the 9volts, and NOTHING, next I blow some air into the input jack thinking maybe some dust or junk got inside again NOTHING!! I don't know what 2 do, my "gain" internally by the dip switches is at factory setting, I tried raising all the way that didn't do anything.
I did notice that my bass eq on the outside has all of a sudden become slightly loose, but I've given up, I don't know if anybody else has experienced this issue, it's come at the most in-opportune time.....thnx in advance!
