From Benson:
Variable attenuator for knocking a few watts off the top, or crank it all the way down to bedroom levels.
Passive attenuator specifically designed for use with the Monarch amp, or any other 8 ohm amp and speaker rated 22 watts and under. For instance: Deluxe Reverbs, AC-15s, Princeton Reverbs. It will NOT work for a 30 watt rated amplifier like the Chimera or an AC-30. We are not liable for improper use of this attenuator. Email us if you want to know if it will work with your amp.
