NEW Cerwin Vega Bass Control Knob and Connection Remote Cable Wire ONLY 4 PIN 

I have no idea what models this was used for. Make sure your amp is compatible.   

I came across a box of these and don't know much about them. Please see pictures for all that you will receive. 

Package will include

• Bass control knob controller 
• Bass connection remote cable "4 pin"
• 4 mini screws for installation
• 1 sticker that can go over the knob to hide screws. 

Last picture shows the knob after you put the sticker on it.
