I'm having a strange issue with my guitars in built tuner. Basically, it requires me to press and depress the button twice before it starts to work.

So, push it once... nothing. Depress it, then push it again, and it works every time. It also works if you push the 'phase' button before pushing the tuner button. Initially, I thought it must be some kind of loose connection. But it seems weird that it works with every alternate push of a button.

As stated in the title, the preamp/ tuner is a Fishman 301T.

Anyway else ever had this issue? I'd appreciate some help.

Many thanks.
