I love it!!!!

Baddass bass knob luv the the design and the the fact that it has a volt meter is a plus d4s is the best

Great product looks bad ass would defff recommend to anyone would be cool to get diff colors made also and the added voltage gauge is a huge plus thanks again will be doing plenty more shopping with y’all once more funds are available

Love the design. Everyone that’s seen it thinks it’s the bee’s knee’s! Voltage readout is accurate. The amount of travel provides a nice roll into full tilt. The variable on/off switch is crisp. My only gripe is the RCA leads could be a few inches longer but it’s realistically not an issue because the connection is snug. Love it!

It was v simple to install plus it looks cool and works great id buy it again ngl

First off this knob is unique and I absolutely love it, design, feel, usefulness of the voltmeter, everything. Has a smooth feel when turning, And simple enough to hook up. On top of this product everything I ordered from D4S is awesome! The customer service is amazing as well and very helpful. They helped me out when little issues occurred and quickly got things straightened out for me! Even ended up getting a few extra stickers in my order for the problems that occurred, as well as offered the option to receive either store credit for receiving the wrong product or a T-shirt to make up for it:) I chose the shirt of course! Was very happy with the help from customer service and again got a few more stickers on top of it all because, well come on, we all love stickers:) anyways. Completely satisfactory service all around and recommend shopping at the down 4 sound store for great products at cheap prices!

First time shopper here and right out the gate I would have to say I highly recommend D4S! Not only are the products of great QUALITY and PRICE, but the CUSTOMER SERVICE is absolutely TOP NOTCH! At least in my personal experience I was treated very well even when there was a slight issue:) First off the subwoofer bass knob V2 is rad as hell, and handy having the voltmeter on hand, (literally) , the potentiometer has A smooth feel and is simple enough to hook up, the interconnects are super snug especially paired with the D4S 2 channel which are very nice themselves! Along with the knob and wires I got some ferrules and heat shrinks which give the setup a nice little touch! But to comment on the customer service now, I always got a kind response quickly and “Avi” worked with me to get things squared away! I ordered the 12’ 2 channel interconnects and in the 12’ labeled package was 10’ wires:/ but when I responded with a pic for proof “Avi” was most helpful, offered store credit for the product and even for the shipping I believe:) and offered also a free T-shirt instead if I would rather choose that (I DID and it was a great pick for a surprise choice by her), And every time I got my products in the mail (which was always FAST, didn’t even need the upgraded mail service!) there was a few extra STICKERS thrown in there! I mean come on! We all love stickers right:) I even feel I got my moneys worth for my second order where I forgot just a few shrink wraps which was half the price of shipping, I asked if they could add it in with my first order so could avoid the shipping but unfortunately that was already sent out, but again got some extra stickers which I was more than satisfied with so, THANK YOU TO EVERYONE AT D4S and look forward to continue using your services for future builds and upgrading what I currently have going on!:)

I purchased this for my son’s bday present. He has 4-15” Nsv4 subs on 2-8k taramps. His previous bass knob worked okay but his amps would protect before the knob was maxed out and his sub level was on -4. We used the dd1 to tune the amps so we knew the settings were correct. After swapping to this bass knob, sub level on -1 and knob maxed out the amps do not protect. I guess the old knob was not as high of quality as this one. Feels smooth when operating and looks cool. Would highly recommend.

Voltage is spot on with dash readout..nice and tough wonderfully made overall great investment

I didn’t get the one I ordered but the one received I’m loving it fits lovely in my hand and it’s blue my favorite color and it still has the voltage read out on it not a bad substitution
