Big Al is my main bass these days but has a little problem that just got worse. I usually use the active/passive button but it doesn't stay down if you switch to passive and then try to go back to active. This started happening in the first 6 months of use, and was not usually a problem because I mostly use active mode. a couple of pushes. and maybe a slight twisting motion and it was fine. Now it is even harder to get to stay down but 20 or 30 clicks will result in proper function in active mode, so I leave it that way. Passive mode doesn't work, though, not without jiggling the button a little. Discovered the jiggle after a gig holding the button down during a show through 2 long songs. Has anyone else had this problem? What did it take to fix it?
