Alpine RUX-KNOB.2 Remote Bass Knob

I purchased this Alpine bass knob because I needed one for my Power Acoustik RZR1-2500D. It’s made of metal and feels high quality.I was hoping this Alpine knob would offer better adjustments than the original one because the original knob goes from 0% to 100% with just about 1/5 of a turn. This Alpine knob is slightly better, it takes about 2/5 of a turn to go from 0% to 100%, giving you a bit more control. So I guess it’s the amplifier itself that causes the knobs to behave this way, not the knob itself.But for $40? That seems a bit steep. I honestly don’t know if there are other bass knob options for my amplifier on Amazon, but this one does work. So if you must, go for it.—????????
