hi guys, i'm new to guitar effects, especially wahs and have a question about my recently purchased used gear.... so anyway i bought a weeping demon from someone for real cheap because they said it didnt work with the battery but wasnt sure cause they didnt have a power adapter to test. well i went out to get an adapter and hooked it up, it turned on and it seems to work fine, all knobs work, the sweep works fine... but only when the footboard is in spring mode. other than that it seems ok, also i noticed when the footboard is released it goes into bypass, is this what it is supposed to do? it it has a distinct cut off sound when it bypasses, as if my distortion effects setting changes, also does anybody know why the battery wont work? also why doesn't the manual footboard setting work? thanks
