This Weber Mini MASS is a compact, passive attenuator designed to let you enjoy cranked tube amp tones at manageable volumes. It’s in good working condition, fully tested and performing as expected. The unit shows some cosmetic wear, light scuffs and signs of use on the case, but nothing that affects its functionality.

Ideal for home practice, studio sessions, or taming stage volume without sacrificing tone. A must-have for players who want to preserve their amp’s natural breakup while keeping the neighbours happy.
