Jim Kelley Power Attenuator 2025 - Gray (Hand‑Built by Jim Kelley)

Jim Kelley Attenuator – Hand‑Built by Jim Kelley (Recent Limited Run)

I picked up this attenuator directly from Jim not long ago, but plans have changed and I need to move it along. This is the elusive Jim Kelley attenuator from his recent limited batch — hand‑built by Jim himself, not the Suhr reissue — and it’s hand‑signed.

This unit includes everything from the original package:

• Kelley pins
• Kelley card
• Bypass plug (for using the attenuator without the footswitch)
• Ultra heavy‑duty footswitch for toggling attenuation in/out

Components:

• Genuine Ohmite rheostats
• Switchcraft connectors
• Dayton capacitors
• Darling switches
• 16‑gauge steel chassis with front panel guard
• Loudness Compensation circuit
• Footswitch interface jack for channel switching or gain boost
• Maximum Power Input: 100 watts

The build quality is exactly what you’d expect from Kelley: overbuilt, precise, and rock‑solid.

I’ve used it literally once with a 60‑watt Boogie Mark II. I paid $1400 with the footswitch, and I’m asking less than that. My plan was to stash it for when I eventually found a Kelley amp, but that looks like it may be a ways off.
