We have upgraded the whole manufacturing process this time to being injection molded & we incorporated a volt meter as well!

The finish is super smooth and soft to the touch.

Still made with the best internal parts and Rca's on the market.

This is one of, if not the best universal bass knob / remote with RCA's on the market.

It will work with any amplifier that requires RCA inputs.
