Das habe ich soeben im Netz entdeckt:
"This is all very good information, but you failed to mention - and what most guitarists don't realize - is that most tube amps (especially vintage amps) are designed to run wide open.
The controls on most tube amps are subtractive, which means when they're wide open, they're doing what the circuit is designed to do. As you back off on any of the controls, you're taking away from what the amp wants to do naturally.
When trying out a new amp or just looking for a new sound, I always start on 10 and gradually back off certain settings from there.
Obviously, there are exceptions to this type of design (specifically Rivera Amps and any active amp circuits), but understanding how a circuit was
designed is very important in understading what that amp is capable of. Remember that most guitar amps, no matter how complicated they look on the outside, are based of some very simple circuit designs that were originally intended for use in radios in the 1920's and '30's.
These radio circuits and most of the guitar (and bass) amp circuits that are based on them were designed by electrical engineers, not musicians. Most, if not all of these electrical engineers did not understand what musicians were doing or what we wanted.
Luckily for us, the things we like about a tube circuit is not what it can do, but what it CAN'T do. Electronically speaking, distortion and harmonic feedback are weaknesses, not strengths."
