Goodrich A7 noise Question

Ken Metcalf · From: San Antonio Texas USA

When I turn on my A7 it makes a swelling sound for a second or so that is pretty loud if my volume pedal is on at all.
and then it is ok.
Anybody have this or know what it is..
Also need a link for Goodrich ... I can't seem to google it..
thanks
ken

Nobody has ever had this sound when tuning on a A7??

Ken: I have used the 7A for quite a while. The only time I get any weirdness out of it is when the batteries are going dead. I assume you have checked this. Happy Trails,Mike C.

I agree with starting out with Mikes suggestion... even going as far as checking any and all batteries in the entire loop. If no batteries, then I'd probably open the unit and take a peek.

This has been doing this for years.. I just don't have my amp on when I turn the A-7 on
and I have changed the batterys several times in that time frame..
I am looking to see if anyone has had the same problem or symptom.

Ken, I always have my amp on first then the 7A. I assume you have tried this?
