Re: Laney VC50 squealing noise!
Hi Richie! Thanks for your answer!  
 
You were wondering if it squeals without anything plugged in. Well, it doesn't!  
 
I've checked the tubes too, they're not microphonic - I've tested moving them around, and still the same noise, and _only_ on the drive channel, with the additional drive stage engaged.  
 
I've bought some Sovtek "high gain" tubes, and I'll make sure they're in the drive+drive stage, then I'll check it again...  
If the squealing still won't give, I'll have to bring it to a tech. I really don't have time for that - our band's got a gig coming up in a couple of weeks. Don't know if I dare gigging with the amp, when it's acting like this...  
 
There's one additional problem, as well...  
I have very little headroom on the clean channel. Can this be caused by the new preamp tubes?!  
 
Thanks for your time!  
 
Tom
