Weber Mini MASS Attenuator - 50 Watt - Good

Weber Mini MASS Attenuator - 50 Watt - GoodWhy This One Good condition - visible signs of use including scratches and general cosmetic wear Fully tested - all applicable functions verified working Reactive speaker-motor attenuation for a more natural load than resistor-based designs Lets you push a valve amp into power tube saturation at manageable volumes Condition: Good This Weber Mini MASS is a good-condition guitar amplifier attenuator. It shows signs of previous use, including scratches, scuffs and general cosmetic wear to the casing, but remains fully functional. It has passed our 9-point functional test, with 1 item(s) not applicable to this unit. Please review all photos carefully, as they provide an accurate representation of the cosmetic condition of the product.What's Included Weber Mini MASS Attenuator No additional accessories included About This Model The Weber Mini MASS is a passive power attenuator designed to sit between a valve amplifier's output and the speaker cabinet, absorbing wattage so the amp can be driven hard at reduced listening levels. Rather than using a purely resistive load, the MiniMASS employs an actual speaker motor to create a more realistic interaction between the attenuator and the amplifier's output circuit, with attenuation continuously adjustable from roughly -6dB to over -50dB. Turning the speaker control to minimum allows the unit to be used as a dummy load for testing or DI use. A front-panel impedance switch covers 4, 8 and 16 ohms, and the unit also provides treble compensation, MASS bypass and a line out. The treble boost counters the high-frequency loss that becomes noticeable at heavier attenuation settings, and no external power supply is required. The 50-watt version is intended for amplifiers up to 50 watts, and pairing it with a higher-wattage head risks damage to the attenuator or the amp.
