Description
Tube Amp Doctor – BIAS Tools The BiasMaster(TM) measures the BIAS current of the most powerful tubes in your amp and comes with an English/German operation manual. It enables safe and easy monitoring of the bias current. As you adjust the Bias control pot of your amp, the BiasMaster(TM) displays the actual results, allowing you to set and evaluate the entire reasonable biasing range that your amp and tubes offer to find and set your ideal choice. The Bias setting significantly affects the amp's response, break-up, and dynamic character.
