The Ultimate Attenuator is the first unit of it's design to lower volume. A reactive load is provided that doesn't need an impedance selector switch on the unit, working with all impedance settings well. Amazing construction with a fun Plexi switch for changing top end response. Other notable features that make this the best attenuator money can buy is an optional 100 volt output power plug that will reduce your amp to that output, as with Variac (Amazing for classic Marshalls).
This is the end all be all device and there is a reason it has been getting so much buzz. Make sure to be the Ultimate badass and secure this Ultimate Attenuator today.
