ABM 5050-V Vintage Tremolo

I changed my Fender US vintage tremolo for the ABM 5050 V tremolo, and immediately I could hear and feel the difference.
The ABM is so much more articulate in the sound. There is a bit more clarity, but at the same time a lot more body in the sound, and the harmonies are more present.
It is very obvious that the hardened quality steel used in all the parts, from saddles, base plate, tremolo block and the 6 mounting screws really ads more depth to the overall tone.

It is also a very smooth action. And it stays pretty well in tune, partly because there is less friction on the string due to the wide saddle holes and the angle in the holes in the base plate.
If you have a well setup bone or Tusq nut and locking tuners, you should be able to stay well in tune.
The tremolo arm also stays in position because of the adjustment screw under the base plate, which is very easy to attend. And there is no wobble in the the tremolo arm, so all the movement goes directly in the tremolo without any loss.
If you have a floating tremolo setups, you can adjust the screw without any problems.
This is a real quality upgrade in tone and action. You can see the quality in the good german craftsmanship when you unbox the ABM 5050 tremolo. This is build for musicians who expect the best from their instrument.

I've used all sorts of trems over the years, Floyd Rose, Kahler, VIntage and modern Fender (six screw and two pin) even in recent years a Bladerunner so therefore feel able to offer an experienced opinion, if only a personal opinion regarding the overall feel, which is very important to me and is why I don't like locking Trem systems (even though they offer the best tuning stability) but as for the feel and sustain factor, feel convinced that 'IF' you play Stratocasters then the six screw system is by far the best even though it is by far the most problematical where tuning stability is concerned. Locking Terms spoil the feel of an old Strat whereas the modern two post trems just don't sound right if you are a fussy old bloke as I am. This is the best 6 screw type I have ever used, it's of top quality, sounds and feels great etc and is MUCH better than the cheap things chucked onto Fenders. Well worth the money, is easy to fit - ignore the 4 star review as I can't give it the 4.8 stars it deserves.

I installed this just because I wanted to get rid of the original trem bar wobble, not believing that the guitar's response will be different in any other way. I installed a Callaham on another Strat in the past and saw no difference, so I wasn't expecting anything tone-wise. I was surprised to realise that the guitar sounds strattier and more lively now. The attack has changed drammatically. No exaggerations here, I remind you, I was expecting no such difference. I'm very happy with my purchase.

Very good quality product.I was a little sceptical but after instalation I realised-it works-it is a remedy,if you have any mechanical or tonal problems with your stratocaster.But do not expect any alteration in your sound-your guitar will sound different,better than before,but still DIFFERENT.I can say only-my old strat sounds better,notes became more separated,but nasal strattiness,glassiness is gone.If you are looking for good quality tremolo without any problems(sitar effect,tuning/pitch problems)-it is your way to go.If you are looking for strat vibe(50's/60's sound),it is not for you,keep your zinc block and change saddles.
