Why I Won’t Use This Guyker TM85 Bridge on My Guitar

Written By: Andrew Siemon


When you’re upgrading your guitar hardware, the bridge is one of the most critical pieces of the puzzle. It affects tuning stability, feel, and how confidently you can play—especially if there’s a trem bar involved.

I recently checked out a Gear-brand bridge that, at first glance, looked very promising. But there’s one design flaw that completely kills it for me, and it’s important to know about it before you spend time or money installing it on your guitar.

You can grab it here on Amazon if you’re interested.


First Impressions: Looks Better Than It Performs

Pulling the bridge out of the box, my initial reaction was actually positive:

  • The overall build materials feel solid.
  • The paint job and finish look clean and well-executed.
  • At a glance, it gives the impression of a decent-quality aftermarket bridge.

If you judged it purely on appearance and finish, you’d probably think it was a good buy.

But the problem shows up as soon as you look at how the trem bar is attached.


The Real Problem: A Wobbly Trem Bar

The core issue with this Gear bridge is the tremolo bar design.

How the Bar Is Attached

The bar is held in place using small set screws (Allen key screws). In theory, this is supposed to clamp the bar securely into the bridge.

In practice, here’s what happens:

  • Even when the set screws are tightened as much as possible, the bar still moves.
  • You can physically push or pull the bar and watch it shift.
  • In my case, the bar could even droop down far enough to touch the table when relaxed.

That kind of movement is completely unacceptable on a trem system.

Why This Is a Dealbreaker

For a trem bar to be usable, especially for any serious playing, it needs to feel solidly connected to the bridge:

  • When you press down on the bar to lower the pitch, you’re relying on a rigid connection between your hand and the bridge.
  • Any looseness, wobble, or play in the bar makes the motion unpredictable.
  • It also just feels cheap and untrustworthy under the hand.

Ideally, the bar should feel:

  • Rock solid in the socket
  • Almost like it’s welded to the bridge
  • Firm enough that the only movement you feel is the bridge itself pivoting, not the bar shifting around in its mount

With this Gear bridge, that’s not the case. The two tiny set screws simply don’t provide the clamping force or stability needed for a reliable trem system.


Why I Won’t Install It on My Guitar

Because of that loose bar design, I’ve decided not to install this bridge on any of my guitars.

Here’s why:

  • It won’t function the way a trem system is supposed to.
  • It introduces unpredictability into your playing—especially with vibrato and dives.
  • It could lead to tuning instability if the bar and bridge don’t return to a consistent neutral position.
  • It just doesn’t inspire confidence when you’re playing aggressively or using the bar frequently.

Instead of doing a full installation and demo, I think it’s more honest and helpful to point out this critical flaw up front. There’s no point in showing off a bridge that fundamentally doesn’t work the way it should.


Who Should Avoid This Bridge (Pretty Much Everyone Using a Trem)

From a guitarist’s perspective, I can’t recommend this Gear bridge for:

  • Players who use the trem bar for:
    • Subtle vibrato
    • Dive bombs
    • Shimmering chord movement
  • Anyone who needs:
    • Reliable tuning stability
    • Consistent feel from their trem system
    • Hardware that can withstand regular use

Even if you only use the bar occasionally, a loose, wobbly trem is more of a liability than a feature.

The only scenario where this might not be a problem is if you literally never touch the trem bar and treat the bridge as a fixed unit—but in that case, there are far better fixed-bridge options out there.


Final Thoughts

While the materials and finish on this Gear bridge look decent, the trem bar mounting system is a fundamental design failure. A tremolo bridge lives or dies by how solid and stable that bar feels, and this one just doesn’t cut it.

Because the bar:

  • Moves even when fully tightened
  • Can sag enough to touch the surface it’s resting on
  • Relies on tiny set screws instead of a robust, secure mechanism

…I won’t be putting it on my guitar, and I don’t recommend that you do either.

If you’re shopping for a new trem bridge, prioritize bar stability and mounting design over cosmetics. A trem that looks good but feels loose under your hand is worse than no trem at all.
