Hello, what kind of Tremolo has an IBANEZ GRG 170DX? Is this similar as Fender tremolos? I know its not Floyd Rose. Are there anny troubles with this Tremolos?

Ibanez wiki says it has a Fat 10 tremolo. Yes, it is similar to Fender tremolos.

Depends what you mean by "troubles". If you intend Slayer like whammy bar action, not gonna happen with that tremolo. Only with a FR type tremolo or a Kahler.

If it's only light vibrato, I think that with a good setup and the nut lubed, you can use it without the guitar detuning.
