Received this as a gift and dont need it . Like New Condition. One of the Best Attenuator on the market Dr. Z Brake Lite good to use on a Amp 45 watts or less . It has 4 setting to lower your volume snd not affect your tone or set it off not to affect you Amp volume at all . Quality built and very easy to mount inside your Combo Amp with 2 screws ( included ) or set it on top of a Amp Head.
