Marshall 30th Anny (6100) loop level question

[SweetPete]

Guys,

When the loop level switch on the back of the amp is pressed in, is that the -10 or +4 setting? The owner's manual doesn't say!

Can't tell you about that particular model, but my old Valvestate has -20dB when the button is out and 0dB when pushed in.

Marshall finally responded to my email. If anyone else cares, it's -10db in the -IN- position.
