Bugera Valves
At a glance, valves may seem to be little more than light bulbs. But when they're in your guitar amp, they are the heart and soul of your tone. That's why they must be selected from among millions to be able to deliver just the right sound. But it doesn't end there; the best ones are then matched into sets that complement each other, ensuring the longest possible life for them inside an amp. This process isn't quick or easy, but we think it's worth it. More...

How Valves Work
First of all, which is it? Is the glowing glass thing in your amp a tube or a valve? The answer is that it's both, but in terms of its function, the most operative thing to do is to call it a valve. Think about how the valves on your kitchen sink work. More...
Valves and Biasing
Like the instruments played through them, amplifiers themselves require occasional tune-ups for optimal performance. In the case of amplifiers, the output valves specifically require adjustment to properly set their biasing (or the optimum amount of voltage running through them) which directly controls power output and signal distortion. Biasing is a special voltage applied to amplifier valves to set them at their best operating point. The optimal bias is specified by tube manufacturers and is the point where the valves amplify most effectively. Valves can't actually be 100 percent linear, but their bias is set to get as close as possible. In fact, the slight non-linearity that exists in valve amplifiers contributes greatly to their sound.
