Designed for transparency and versatility, the Power Attenuator employs two rheostats and a Treble Boost Switch to preserve the natural characteristics of your tone.

TREBLE BOOST SWITCH

When listening to music at lower volumes, it’s natural for a signal’s high-end and low-end to become less prominent. This three position switch works as a loudness compensation to restore top-end dynamics to your guitar’s signal when playing at lower volumes/higher attenuation settings.

TONAL TRANSPARENCY

The Jim Kelley Power Attenuator is designed to be as transparent as possible, preserving the dynamics and nuances of the tone you’ve worked so hard to craft.

FLEXIBLE CONNECTIONS

The Jim Kelley Power Attenuator gives you two speaker outputs wired in parallel, along with a line output derived from the attenuator speaker jack. The line output is useful for sending your amp’s attenuated signal to a PA or recording console for further processing.

IMPORTANT

The Jim Kelley Power Attenuator is not a load box/dummy load. Always make sure that your amplifier is connected to a speaker to avoid damage to your amplifier.
