Review on 🔊 CT Sounds Universal Bass Knob - Digital Voltmeter, Blue LED Display, Remote Gain Control, Power Switch: Enhance Amp Performance with Durable ON/OFF Push Functionality by Mike Ken

That's why I give it 3 stars. Pros: • For example, I can still control the display to turn off. • Finally a level controller and a voltmeter in one device. • large handle and on/off switch. • the handle does not click. Disadvantages: • Pen. The handle falls off. I wish it was a little tighter. This way we can actually determine the level we want to reach. In a noisy system, the handle can move or tap freely. • I'm really not sure if the voltmeter is autoranging or if we should be adjusting it. I have a clue for you. • wires. The base and the remote control are pretty much all I need. Some don't have extra space behind the dash. But overall this product is good. I wish we had a backlight on the universal grips.
