I purchased the Hipshot Bass Xtender for my new Fender jazz bass. It works perfectly and allows me to drop my E string down to D in the matter of seconds.

I have the pleasure of buying from Fat Tone. What I get from them is a personal connection with them every time I make a purchase!

Sppedy delivery to Australia no issues.

Works like a charm, much better match for the newer Fender tuning pegs.

I've been using Hipshot Xtenders on several of my basses. I rarely use a 5 string and the Xtender affords me the ability to drop the tuning on my E string to a preset tuning (Eb or D) which covers nearly all of my needed applications. You just tune it normally then release the lever and use the thumb screw to tune it to the lower note. Return it to the original position to get back to the open E. It's just that simple.
One thing I would encourage you to do is to make sure the "E groove" in your nut is smooth and the string moves freely through it, especially if you're using round-wound strings. If the string isn't moving freely it could affect your tuning when you return the lever back to it's original E position.
You can actually add a "double-stop" lever to some of the Xtenders that gives you a second tuning position.
