As we all know, tube amps provide the best sounds at higher volume levels. If you lower the volume, you never get the excellent saturated power tube sound. Preamp tube distortion and power tube distortion sounds different and many guitarists prefer the natural overdriven tone of their “cranked up” tube amp, especially when the power tubes are being driven hard. (most guitarists prefer tone when the power tubes are driven hard.)

However, the volume level at this point is often too loud for small stages, studios and houses. While the cranked up amplifier may sound and feel good to you, it might not be tolerable by people around you and it could eventually cause you permanent hearing damage. This is where the Watt Killer comes into play.

Watt Killer is a power attenuator that we designed it to get the “cranked up” sound of a tube amplifier at reasonable volume levels. It allows you to drive your tube amp harder and keep the desired tone without blasting your ears and disturbing anyone.

It takes its place between your tube amp head and your speaker, and reduces your tube amplifier’s output power before it reaches speaker. You can use with the amps up to 100W power at the whole impedance choices (2-4-8-16 ohm).

You can keep the volume of your amplifier as high as you want, and control the actual volume in the room by adjusting the output level on the Watt Killer as a “master volume” control, sets the overall volume of the speaker.

When you use Watt Killer at its maximum level (4th level), it lowers the volume as ~35 dB.

Please note that SPL (sound preasure level) in dB and Output power in Watts terms in an interaction by logarithmicly. Even a cranked 1 Watt amp sounds loud, you should accept that you need  understanding neighbours while playing tube amp in your house, altough Watt Killer.

Also the bass response of human hearing is seriously reduced at low volumes. This is the main reason why amps played quietly not sounds so good, except power tube saturation and speaker distortion. We also added a passive low pass filter to Mk.IV edition to compansate hearing tune.  It works all attenuation levels and cutoff frequency of filter changes according to attenuation level.

We also added a cooling fan, a line level output and its level control knob placed at the back side in the new Mk.IV version. It's still a passive device and doesn't require an external power supply. The fan operates by the current supplying the loudspeaker, provided by the amp.

The line level output can be used only when the speaker connected. Watt Killer doesn't work like as a dummy load or a load box yet. But we're working on it.

Finally, Watt Killer only “kills” the output power of your amp, not your Dynamics, tonal quality and feeling. You will get almost the same tone as when playing the amp at full volume, only not that loud. You could have power tube distortion tone at any volume you desire. Sure, there is no way to get the tone you get with the Watt Killer by using any pedal.

It is packed with 1 mt. connection cable.
