price is a little high, and on top of that paying for the shipping, but when one of these breaks (or your buddy busts it) you gotta pay the piper. it works, except don't assume you can use the whole range on the knob. it only affects the bass output during the first half or less of knob travel. the cord is nice and long though that was a good touch, and having a standard 3.5mm plug too!
Messed with it tonight. Like another review stated it rotates like 270 degrees but its useful range is like 0 - 35 degrees, after that point there is no increase of volume. Still works though and sure beats having to change the bass settings through the head unit.
This is a great remote for an incredible amp. I have had so many different types and brands of audio equipment including Rockford Fosgate, JBL, Sony, and Pioneer. I keep coming back to MTX and it has always been a better quality product than any other brand.
