G'day mate :),

Does the desk hum?

G'day there Skippy Ranger :).
We are in for the first cyclone of the season next week here in the FNQueensland .

The desk is fine all channels are quiet , its a passive sound craft , must be 10 years using it now and it all works . knock on wood ...
The only problem with the desk was a pesky rat or mouse that liked to chew one of the knobs when we left it set up on Dunk Island .
Funny thing is it went for that same knob and chewed half of it off , I didnt realise what was going down in the middle of the night...lol

AH ha , I just recall , the hum actually went away when I earthed it ( touching the input jack ) , and came back after about 5- 10 seconds ( after unearthing it )
Just in case that could help in diagnosis

Have you tried any other instrument to see if you get a hum?. I am just trying to see if you're getting a loop hum or if in fact the pickup jack is the cause.

I plug other guitars in through the same fx pedal and leads with no hum

Well mate, looks like you unfortunately, answered your own question. I would be checking the connections on the acoustic now.

If earthing the guitar jack to the desk works, then I'd be quite happy, and if swapping the lead shows it isn't a cable fault then it's perhaps the jack - but if connecting an extra ground works, why worry?

Yes I guess Ill run an extra lead from the input jack to the chassis of the desk . It just bugs me that surely it should be working properly without having to go there .:whistle:
