Thanks for the answer.
I finally understand now.

I got a strange problem with the Liverpull. It seems to have lost some power/volume. Occasionally the volume jumps up. Like some invisible
person turning the volume knob up and down again.
It the same sound no raise in gain.
I changed all the powertubes to new ones. - Same problem.
I put in new preamp tubes. -Same problem.
I play the amp thru a Marshall Powerbrake. I tried the Powerbrake
with another amp. - No problem with the PB.

Any ideas?

I have just gotten my Liverpull. Sounds really good. A real one trick pony but does exactly what I want. Howerever; the strangest thing- the bass knob acts like a
mastervolume? I tried to get a explanation from Nik about this but havn´t heard anything yet.
Anyone else with this kind of problem?
