    I just installed this on my latest build and so far it works flawlessly. I would buy again if I need another one.

    Honestly I wanted something as simple as not having to reach under my steering wheel, on the plus side it has an off switch. I love it.

    Super smooth!

    This bass knob is super high quality. Very sleek look and fits perfectly in my hand. Super fluid turns and it’s not too tight, I can easily turn it up or down with a single finger. The price might be a bit more than some want to spend for a bass knob, but I highly recommend this product for any basshead. Thanks Down4Sound!

    Worth the wait!

    I had my eye on this bass knob for sometime now. It’s not that I was on the fence about it, it was always sold out. Lol. Very comfortable in the hand. The voltmeter is spot on. I’m coming from a PAC-LC1 universal volume controller, the wait for this bass knob was extremely worth it.

    Metal Bassknob not working properly

    Posted by Javan Mackenroth on May 18, 2020

    Hello I am have issues with this knob, the colts are inaccurate as well as the top leds not working. 7 volts looks like 1 volt.
