I tells you. This thing is the spawn of Satan. It seems possessed. So we have the mysterious ghost in the channel switching and now the flies have taken possession of everything. Sounding like a grounding problem.
Well, it is a grounding problem. Touching the chassis or the guitar causes the buzzing to go away. Heavy buzzing with single coils and humbuckers.
Biting the bullet and sending it in for a warranty repair. Just need to work out who its going to.
Sorry you're having so much trouble with that one. That's the first I've heard of Laney playing up - they must have beaten the shit out of it in transit
Nope. Amp into filtered four way into wall socket. It has developed this hum anyway. It wasn't there last week last time when I played loud. It comes into play at about 11 o'clock.
Can't find an phone number so I'm going to email them. Hopefully they will be as good as Marshall in getting back to me.
Just a suggestion, but perhaps one of the ground wires is loose? A bad solder joint or something? Perhaps the amp chassis is intermittently losing it's ground-shield connection?

That's what I'm thinking and I really want to take a look. But if I do I invalidate my warranty or at least I think I might. Otherwise I'd have given it an hour and ripped the chassis out to have a look myself.
One thing I did notice was that moving out of my usual playing position reduced and almost removed the buzzing. So I'm kinda thinking that maybe it is not the amp and something environmental. I don't think the buzzing was happening when the guitar cable unplugged.
Do you have any halogen lights running on the same circuit, on another circuit in your building, or on any circuit within a 600-mile radius of your amp? Those can create nasty interference, as can fluorescent lights, electric motors, and computer equipment.
If changing your playing position changes the amount of hum you hear, move your guitar around until you've diminished the hum as much as you can. At that point your headstock will either be pointing at the source of the hum, or else 180 degrees away from it. It works here anyway, including devices on the floor above me when I'm in the basement.
See I tried that, and it didn't really point towards anything. As I live in a flat I really have no control over a lot of environmental factors above and below me.
It was probably just the girl above me trying out her new vibe or something.
