hi guys,

hopefully someone can help..

I've recently decided to start using the fx loop on my amp more (had it a while now, but never really bothered)..
anyway.. i've noticed today there is a static buzzing sound when the fx loop is 'on'.

on - as in on the back of my laney vc30, the switch from bypass - 5db - 10db...
on the 'bypass' slot its fine, no interference or buzzing..
then on the 5 and 10db it is progressively louder..

any ideas what it is?

This is your VC30, yes? They have an op-amp buffered loop so it won't be a tube. Try cleaning the sockets. Spray some contact cleaner liberally on a plug and work it in and out of the sockets a few times.
