ABM 2400g-RO Roller Bridge G

Un puente como éste, al que se le supone una elevada calidad, fué el idóneo para la destinataria, una Gibson SG 2013 Deluxe con un Bigsby, que desafinaba como Dios manda que desafine un Bigsby. Jaja.
Todavía no me acabo de creer lo que ha mejorado : sin haber tocado las selletas, me encuentro con un quintaje casi perfecto y, lo que es mejor, casi total ausencia de desafinación, por más que abuse del Bigsby (todo hay que decirlo, siempre lo uso para aflojar las cuerdas).
En mi caso particular, va a resultar que no tendré que tocar la cejuela, y ni siquiera he tenido que recurrir a un Luthier... lo que menos me esperaba.

This bridge looks good and works very well.
I have a Gibson ES345 with a Bigsby, and though it didn't really have tuning problems, the factory bridge was really getting old. The saddles were just too worn.
So I bought this bridge after hours and hours of reading blogs and reviews.
Some stating that roller bridges kill tone and sustain, some stating that they exalt the tone and improve sustain.

I'll be very honest: I tested the old and the new bridge, A-B'ed them many times. I carefully recorded them in Pro Tools in my recording studio with top grade gear.

There's no significant change in tone or sustain.
They didn't really sound 100% the same. But the difference was like a 3%.
And none of them sounded better than the other.
I mean, if you slightly move the knobs on your amps or guitar, the difference will be A LOT bigger.

What DID change is the action on the Bigsby.
Again, the factory bridge worked quite well. This new one is just a bit smoother, the Bigsby feels a little better.

The tuning stability on my guitar is really great at this point.
The guitar itself is well setup and stayed in tune well even before changing the bridge, but now the stability is just shocking.
My Bigsby has the Reverend "Soft Touch Spring", which is much softer and smoother than the factory spring.
That made a huge difference.
This bridge is just the icing on the cake.
Now everything is perfectly smooth.
I can basically use the bigsby like the tremolo of a strat.
It's drastic. It's very good.

SO, to wrap this up, if you have a high end guitar and you're looking for something that will "drastically change" or "considerably enhance" the tone of your guitar, I didn't really find this to be the case. My guitar sounds almost the same as it did with the factory bridge (which is a good thing because it always sounded great).
If you have a cheaper guitar, and you're looking for a proper upgrade in functionality and sound, this is what you're looking for.

I'm guessing this bridge is of superior build quality compared to a factory Gibson bridge. The materials should be better and more durable.
But I guess only time will tell.
For now, I'm just happy with the results
