Allparts Tremol-No Pin Type

I decided to renovate a Japanese super-strat that I've had since 1987. It has an un-licensed(!) Floyd-Rose style trem with a locking nut and fine tuners at the bridge. While I blocked the trem during set-up I noticed that the sustain doubled and the guitar was objectively louder, even when played acoustically. I considered for a moment the idea that I might block it permanently, but after some research discovered that this Tremol-No upgrade gave the trem the same properties without it being permanent.

The device replaces the claw with its own, and adds a rod-within-rod mechanism that sits between the springs. A clamp attaches firmly to the bridge block from the other end of those rods. When the trem bar is flattened one rod expands, when the trem bar is sharpened the other rod contracts. Both rods have pressure screws that restrict movement for a given direction - in fact the expansion rod has two screws to double the locking strength so you can break a string without disastrous consequences.

It is a lot neater that gluing pennies between the bridge block and the body routing of the guitar, and as I said, you can decided from minute to minute if the bridge is floating, back blocked, forward blocked, or both.

Installation was fiddly, but not impossible. I also note that the single screw section doesn't really get tight enough unless you remove its O-ring.

The Tremol-no is a device which , when installed in a guitar with a floating tremelo system, can be used to either prevent the tremelo form rising out of the guitar's body, effectively making it a "dive only" tremelo(reducing the risk of string breakage, or it can be used to lock the tremelo down completely, as if the guitar had a fixed bridge. This can be done by fastening the screws on the tremol-no.
The tremo-no is an invaluable piece of equipment for the guitarist who needs to alter the tuning of a guitar, who would in any other case not be able to because of it's floating tremelo system.
I use the tremel-no to change between standard and dropped tunings on my guitar which has a "Floyd-Rose" tremelo system. Without the tremol-no, this wouldn't be possible.
If I were to have a small qualm about the Tremol-no, it would be that in order to fasten the screws which either fix or limit the tremelo's ability to move freely, excessive force is required to ensure it is absoloutley tight.
In conclusion, the All-parts "Tremol-no" is a useful piece of equipment for the guitarist who has a guitar and needs it to do everything - at once capable of string snapping dive bombs and vibrato, the tremol-no will fix the bridge of the same guitar making it perfectly versatile.

My intention was to use this on a Jem Jr. Its Floyd Rose is not the best, but I would block it to only one direction anyways because I wanted to use an EVH D-Tuna.
Pros: The Tremol-No is very intelligently designed, you can tighten the screws so the bridge can be fixed or blocked or set free. Installation was really easy and it was working fine.
Cons: The screws are hard to tighten and hurts your hand. And if you can't tighten them, they won't work.
Eventually I took this out because it's overkill for the job that a wooden block would do better in my case. But If you aim to be able to use a bridge in more than one configuration, you should give it a try.
Maybe the manufacturer should consider designing more friendly screws for the bare hand, or enable screwdrivers.

The tremol-no really addresses any issues a guitarist might have with either tuning or else playing country style bends on a guitar with a floating bridge.

It works really very well and is very convenient when you want the best of both worlds. It also has increased the sustain of my Fender Strat a bit as it is more dense than the previous springs.

I bought this product 2 years ago and have had it installed in my guitar since. The instruction manual is very easy to follow and can be installed very easily or else if you're not comfortable by a technician.

My only criticism is the knobs have a tendency to fall out and get lost. However I emailed the company directly and they were more than happy to send out replacements free of charge.

Would recommend this product.

Such a simple design, yet it works perfectly.
Bought this for my Cort G260 OPN as I didn't like the way the tremolo dipped when I went to an open tuning or even into drop D and just keeping it hard-tailed wasn't cutting it for me.
The installation was really simple and the setup was just the same. It even has some hex screws on top of the regular trem screws to keep it even tighter.
Being able to change tunings on the fly and still use your tremolo after it is a huge bonus, the Tremol-No is just amazing. Haven't had a single problem with it yet, maybe just that I don't know how to setup the dive-only mode (perhaps I screwed up while installing it, but oh well)
Would recommend this to anyone who wants to change tunings at their will but also use the tremolo in whenever they want to.
