Product details
The V3, ZA3 amplifiers are equipped with replaceable knobs. Customization of the amplifier's appearance, makes it easier for users to tailor their setup to their individual preferences.
To replace the knobs, Just need a cloth with friction, simply grasp the existing knob firmly and pull it straight off the shaft. Then, align the new knob onto the shaft and press it firmly in place. Make sure that the new knob is securely attached before use.
Tips: The V3, ZA3 knob only fits the V3, ZA3 and is not suitable for installation in other amplifiers.

You know I needed to swap out that black GR70 with an orange one! Damn. It’s so much better. Fosi. Make it all orange by default. Make the black ones the optional ones to buy! ❤️🔥
This orange knob makes the two amps from Fosi go together great! Great service as always
Now it matches my main amplifier
Purchased this black knob to substitute the orange one. The quality is good but I did have to modify the inner plastic bushing to make it fit. But overall I am happy with the results.
Nice update. Super fast shipping!
The orange knobs on the ZA3 are very eye-catching, but the black knobs look much better in my house.
The orange knobs from Fosi Audio are an excellent purchase: well-built, easy to install, and with a vibrant color that adds personality to the audio setup. They offer a significant aesthetic and tactile improvement over the original knobs, making the system look more professional. Recommended for those seeking quality and style
Works great easy install. Wanted to switch up the look of my unit and this does 100%
simple easy perfect
I have two za3 and I noticed the orange knobs had slight different shades of Orange. I contacted Fosi about it and they compensated me directly by reducing the price on one of the ZA3. I ordered a new knob and now they have the same color. Fosi is a great company who really listens to their customers. So friendly and accommodating.
Good quality material. Easy to replace.
Fosi Audio Replaceable Orange & Black Knob
Fits and works like it's supposed to. Everything a knob is, and nothing it isn't.
The Fosi Orange replacement knob really looks great on the V3! Much easier to see the volume level than the original black one. Great match for my Fosi P4 and P4.
Great thing to modify your Z series!
I have a V3 amplifier that surprised me with its excellent quality. Fosi Audio has proven its high product standards, so I bought the high-quality ZD3. It has a beautiful, modern look. And so the stylish DAC would match the amplifier, I ordered an orange volume knob. Now it all feels like one family. Thank you �� I��m very satisfied.

I finally received this. Thank you
It looks very good. I'm happy ??
Fosi Audio Replaceable Orange & Black Knob
Great product, I am very satisfied.
Couldn't stand it. Had to have the orange metallic vol. Knob. I feel whole now.
OK, so my GR70 arrived with a black knob and I wanted orange. Jumped on the Fosi website and yes it was available, cheap and freight cost free. What more could I ask for?
Arrived on time as described
I replaced the original volume black knob on my Fosi GR70 with an orange aftermarket knob and painted white the small dimples on the tone controls. I really like how my GR70 looks now. Cheers Fosi!
I like the orange than the black one. More appealing the the black.
PERFECT
Very good quality. Easy installation / switch. Looks great.
Add a great look to the device.
I wish Fosi offered a silver or aluminum finished knob.
I thought the black original volume knob looked a bit dull, same as so many over the past 30 or more years. The bright orange one added a bit of bling, a bit of sparkle, and also made my tiny V3 look like an instantly recognisable Fosi product, we I found very appealing. Not many things in life are perfect but I believe the orange volume knob is a perfect addition to a perfect amplifier. Enough said! 100% recommended.
