More often than not, your amps output is more than your ears can handle. To maintain the tone of a cranked amp with saturated tubes and output transformers, a device called an attenuator is placed between the output of your amp and the speaker. Weber offers a variety of attenuators for different applications.

A note about the power level: You should select an attenuator that can handle at least as much power as your amp puts out. Amplifiers are generally designed to operate clean, and most manufacturers specify the output power as clean power. When you run the amp full blast, the output devices actually become more efficient because distortion is not considered. Under those conditions, the amp may be capable of putting out as much as 50% more power than its rated clean power. Be aware of that when choosing an attenuator, because the idea of using an attenuator is to run the amp full blast into power tube distortion and then controlling the level going to the speaker. If you are going to dime a 50 watt amp, you should choose a 100 watt attenuator. |
Two types of Weber
Attenuators:
|
|
|
|
Resistor |
Speaker Motor |
Some Weber Attenuators use power resistors to effect a purely resistive load on the amp. These attenuators are much like the other attenuators on the market, and provide a less natural sounding tone when heavily attenuated. Our resistive models are the High Power Load Dump, Low Power Load Dump, Mega Dump, and Headphone Tap.
Other Weber Attenuators utilize an actual speaker motor to apply a reactive load on the amp. The attenuators are unlike any other on the market, and provide a much more interactive, natural sound when in use. They affect the tone less than the resistor-based models. The speaker motor units are the MASS, MiniMass, MicroMass, Stereo MASS, MASS 150, MASS Lite, and Power Tap.
Lead Time
Please be aware that most of our products, including Speakers, Attenuators, and Bias Rites, are hand-built to order, to ensure the highest quality. This means that you will need to allow at least 7-10 working days for us to complete your order, and then ship. Once your order has been shipped, we will email you the tracking number automatically.
We answer as many status requests as we can.
Please note that status checks within 7-10 working days of your original order date may be difficult to answer.
