Hi guys,i was hoping some of you could shed some light on this problem for me.

I use an Ashdown Mag 300 Evo II head through an Ashdown 4x10 cab.

Recently whilst playing, the cab starting making an unbelievably high pitched squealing noise(at all volume settings) and I felt an electric shock run through my bass.
Now everytime I even turn on the amp the speaker makes this noise.

I'd really appreciate it if someone could help me understand whats going on?

Thanks anyway guys.

Will Lane Hi Will,yeah the plug is standard 3 prong.

Ive had the head and cab since new and they've run perfect together for the last 4 years.
