Hard to find Ultimate Attenuator. These have an outstanding reputation for producing the most realistic attenuated sound for high power amplifiers.
For use with 16 ohm loads. This Ultimate has the "Bedroom" and "Plexi" options. The "Bedroom" option attenuates to a very very low level, while still being very sonically accurate. The "Plexi" option is meant to give that sonically 'warmer' tube tone found in Marshall Plexi amps. Comes with power cord, usage instructions and original box.
