Weber mass 200 attenuator ,and jumper cables to make it compatible for a combo amp. Weber recommends this for amps 100 watts or lower. Can work with amps 4, 8, or 16 ohms. This is NOT recommended for 2 ohm amps such as tweed bassman, or super reverb.
At full attenuation ,this attenuator brings my fender custom vibrolux reverb (40 watts) down to about conversation volume with the amp fully cranked. Has variable treble compensation knob which comes in handy for heavy attenuation.
