For stage use, it is a useful tool to limit your overall dB level at any time during a performance.Let's say you want to warm up your output tubes but the club is not full yet.

As the night progresses, reach back and remove degrees of attenuation until the desired level is reached. This will allow you to manage your amp's overall volume without varying from your amp's favorite settings.

At home, THE MASTER VOLUME attenuator is useful for lower volume while still allowing for full output tube distortion. It has a "bedroom" level control that, when selected, will allow for fine adjustment and maximum attenuation down to 1 watt (with amps less than 100 watts.)
