Guitar Gear Review: TiSonix Titanium Locking Nut

The official description is “Made in USA. Body and clamps are formed from heat treated titanium for incredible strength– designed to secure grip, resist string grooves, and ensure that the threads will not distort if the clamps are over-torqued.”

I have to say that I’ve really been enjoying the journey through titanium parts for my double-locking tremolos. What started with saddles and mounting studs (both also made in the USA by TiSonix) expanded into titanium sustain blocks.

The titanium locking nut is something I’d been eyeballing for some time. And then you wonder if the value validates the cost. Let me tell you…if you want a reliable locking nut that is precision crafted, clarifies your tone and increases sustain…then, yes…the value is more than validated.

You get an entire assembly. Nut, nut blocks, block screws and all the screws needed to mount behind the neck or on top of the nut shelf. So, yeah, everything you need. At first look, you can see that it’s a precision crafted piece of titanium. Lines are precise.

Speaking of precise, I’m the sort of dude that wants to be thorough for you, gentle reader. So I pulled out the calipers and referred to the established specs. The TiSonix titanium locking nut is dead-on to spec. Many of us that have dealt with out-of-spec parts for our double-locking tremolos can appreciate that level of precise dedication.

It installed like a champ. This went on my Charvel® Guitars Made In Japan Pro-Mod San Dimas® Style 1 HH, which already has the titanium mounting screws and titanium saddles, both made by TiSonix. A quick review of the action and intonation and I was off and running. As with all my existing experience with titanium, it opened up the tone. Since titanium doesn’t really “take” or “rob” the energy of the strings, it lets your guitar do more of what it is intended to do. It doesn’t enhance, as much as it gets out of the way. Some people think it brightens the tone, but it seems to me that it replaces parts that were soaking tone out of the guitar.


Chords are well-defined and roared with added resonating sustain. If tapped and pinched harmonics could squeal any more or any longer, it would be from the satisfaction in how they don’t just pop out so much more pronounced…but also in how they sing so long that you’ll think you have a sustainer built in to your guitar.

How does it stay in tune? I ran it through my ups and downs. Then I found a buddy that eats locking trems for snacks and let him abuse it for a while. I found it to stay in tune exceptionally well, leaving total confidence of coming back from a dive bomb or a Dime/Vai-ish squeal to an in-tune guitar.

Take that money you were going to throw away on a stomp box that alters your tone and will be in your junk drawer within a year. Make a solid investment in a part that will unleash the tone that’s already in your guitar and waiting to get out.

Don’t have a double-locking tremolo? You’re more of a traditional player? You’ve come to the right place. How about a review of Gibson-style titanium parts? ABR bridge/saddle assembly…locking posts and thumb wheels…stop tail piece…. and locking studs? Well, then…..stay tuned in upcoming weeks.
