F-50 Hissing

[barneyc4]

Its my first tube amp. I noticed that when idle (nothing connected to the amp) and the master volume at gig level volume, the hissing is louder than in most solid state amps. No crackling noise or anything, just simple hiss. Hiss is in all channel but louder in the contour mode. Is it supposed to be like this?

The amp has always been like this, since new. Im just double checking hehe.
I also slightly tapped the tubes and no noise or crackling sounds.

How do you handle the hiss when recording?

im new at tube amps.

Try changing out your pre-amp tubes one at a time with a new spare and see if that doesn't help with the hiss.

Hissing could only mean one thing............THERE'S A SNAKE IN YOUR AMP!!!!

Now for real:
A tube amp will hiss more than a solid state amp, but if it's abnormally loud then it is probably a preamp tube. Some solid state and almost all modeling amps have noise gates or a noise gate circuit in them that makes them run quiter at idle.
