Bass drop out issue

[dmccombe7]

At rehearsals on Sun i found that certain notes on certain strings were dropping out ie B on the E string most noticeable. Playing at higher volumes with GB stl 600 and Berg cabs mounted on a Gamma board.
Couldn't understand it so decided to try the studios EBS amp in parallel with my GB and into seperate cabs. Still same so put everything back together however when doing so i noted that one of the plugs on GB wasn't in fully and clicked in place.

Hey Presto problem solved.

One for the note book to all to double check plugs are in and secure i guess.

Cheers
Dave
