The Mockingbird

Passive Stereo Speaker Attenuator for Low to Mid Wattage Tube Amplifiers

8 Ohm Stereo

The Mockingbird 8 Stereo 65W attenuator was built on the success of the Tweedy Bird and Black Bird attenuators with 2 discreate channels of attenuation controlled from one knob. Each channel has a true bypass switch. This affords the ability to run one amp/channel at full volume, such as an isolated mic’d cabinet, and one amp/channel attenuated, such as an in room monitor cabinet.

Blackout Tweed, Black, or Blonde Tolex (Specify when ordering). Hammond aluminum enclosure, SOZO bypass capacitors, Switchcraft jacks, Carling mini-toggles, vintage style cloth wiring, and large rubber feet included.

Detailed attention to preservation of high frequencies, at low volumes, was the key focus of my design. Many hours of design/research and testing have yielded fantastic results! Even at the lowest volume settings, (90db typical at speaker), most of the high frequency content stays intact. There are no switches to flip or buttons to push. Simply plug the output from your amplifier into the Amp in and your speaker into the speaker out and dial in the volume you are looking for. A true bedroom volume practice amp from your stage rig!

While the passive load is rated at 150W RMS/300W Peak, I do not recommend use at high attenuation levels and extended periods of time with Amplifiers over 85 Watts. This allows for some headroom for sufficient cooling and component longevity. With all of this being said, if you are looking for the perfect low volume recording situation for your current stage rig, I would spend the $200+ on a Weber Reactive load attenuator. The Physics behind Ted’s design is solid and well worth the $$ they garner. However, if you are looking for the BEST sounding passive attenuator for low volume practice/rehearsal and writing/recording demo tracks, or to tame your stage volume, look no further!

Disclaimer: The attenuator must be connected between the amp and speaker using the proper jacks (i.e… Amp jack(Red) goes to Amplifier Output and Speaker jack(Black) goes to the Speaker). While holding the attenuator with the volume knob facing you and the jacks toward the top, the amp input is to the left and the speaker output to the right. Connecting the attenuator in reverse can seriously damage your Amplifiers output transformer! DON’T DO IT! I will not accept responsibility for any damage associated with not following the included instructions for safe and reliable use. YOU HAVE BEEN WARNED!
