1 Danny 1 year ago Hello Everyone, I've realized that my 2005 Annie 'mud switch' is actually working properly. It adds treble and chime when in the down position, and kind of darkness (definitely not bass) on the up position. This makes it quite useful to get a bit of presence in solos, etc. For what I read, the mud switch is not usually that useful, so I wanted to make sure: Is there any circuit change in that year models? Thanks for your answers / feedback!
