Stuck tremelo on 210HD-130

Often times when I power up the amp from standby,
the tremelo is 'on'..as if it's stuck. It hasn't been left on by the pedal because I rarely use it, however; sometimes I have to use the pedal to turn it off or if that doesn't work, just turn all knobs (corresponding to tremelo) down to zero and after a few minutes, it
shuts off by itself. Last night got weird because in the middle of playing, the tremelo just fired up on it's own???
Is this a bad pedal (original) or something more.
I say pedal, because sometimes I can't click off the reverb either...
thanks.

sounds like a ghost to me

Those ground to shut them off so it's not getting grounded when you DO shut it off. I've got to say the switch is opening up. Check the continuity on the swicth for full contact. Mike.

thanks!

Well Ben,you got a couple of quick responces on your prob,you can go with Mike's answer(recomended),or you can have a exorcist come over and fix your amp.
