high pitch noise

[Model 6 Matt]

hey all, just got a traynor ycv 40 and i like it alot, but there is one thing bothering me at the moment, when i turn the volume and gain up, i get a really high pitched squeal, to solve it i have to turn the treble down, or the gain, is this common in tube amps?
Ive never owned one before so be nice.
If not normal, what should i do about it?
thanks

Yes, it's called feedback. Stand further away from the amp and/or don't point the pickups right at the amp.

i tried standing back, still happened, maybe a preamp tube is dead or dying? im not 100% sure?
Cure i guess is to roll off the treble or gain.................

.. ok.. maybe a preamp tube, or your cord..or something in the signal chain like a bad jack in the guitar or a pedal.

Yeah. Using a noise gate/noise suppressor will help, too.

1) Open Amp

2) Remove squealing pig

3) Fry said pig to golden brown

Said pig can also be found in a certain thread over in Artists...
