Gibson Power Stealth 8-ohm power attenuator in very good condition. Designed by Andy Marshall and hand-built in the USA by THD Electronics (Seattle), this is a limited-edition / rebranded THD Hot Plate in the distinctive gold & black finish.

Key features:

•  8-ohm version

•  Rated up to 185 W max

•  Stepped attenuation (–16 dB / –12 dB / –8 dB / –4 dB / 0 dB) plus variable attenuation control

•  Load switch

•  Bright and Deep tone switches

•  Bulbs On/Off switch

•  Dual speaker outputs

•  Line Out + adjustable Line Out Level

•  Balanced XLR Line Out (600 Ω)

•  Auto fan cooling

The variable attenuation gives you finer control over volume reduction beyond the fixed steps, making it more flexible for dialing in exact levels. Reactive load design preserves the natural feel and response of your tube amp while allowing you to push it hard at manageable volumes.

Condition: Very Good. Fully functional, all controls and switches work as they should. Cosmetics show normal light wear consistent with careful use — no major damage, dents, or issues. Clean and ready for the board or studio.

What’s included:

•  Gibson Power Stealth attenuator only (no box, no cables, no documentation)

A capable, well-regarded attenuator from the THD lineage in the less-common Gibson goldtop finish.
