Can hear guitar when amp volume is all the way down!?

Like it says...I rebiased my amp yesterday and played with my band last night -all was well. Plugged it in today and I can hear my guitar when the volume is all the way down to 1. What the hells that mean??

It's just the way the amp's designed. It just means that when turned right down there isn't a complete short to ground on the grid of the associated tube. It can happen sometimes when you have a dodgey pot or it could just be the way it is.

Would that sound familiar if it was a '73 super reverb? Don't remember this happening before I rebiased the amp. - as in before yesterday

On a Super the signal should be taken directly to ground at the grid of V1b so you really shouldn't hear anything. Sounds like the pot is on the way out. I'd replace it before it gives you real problems.

My 6505+ does that, as does my friend's Triple X. I always assumed it was just normal in some amps.
