I'm about to buy a new guitar, and have doughts regarding the one to choose:
Ibanez GRG170DX
Ibanez GRG250DX-BKF

I'm posting this question, so you can help make my choice, if you have other guitar of the same price(apx) and better, that would also be good to know. And i whould also like to know a good begginers amp for abou 100€/$.

Best Regards & Thanks in Advance,

Best beginner's amp for 100 euro is the Roland Microcube. I think it sounds great, even better than some bigger and more expensive amps. You won't regret it.

I have an Ibanez GSA60, which is ok. It's quite solid and it feels great to play, but it does have problems with staying in tune, and it doesn't sound very good. The GRG170 is very similar.

If you get any of these guitars, don't expect to be using the tremolo. It won't stay in tune. The GRG250 has a locking tremolo, but don't let that fool you, it's not a very good one. I don't think it's worth buying since it just makes it difficult to change strings.

For other guitars in that price range, I'd recommend having a look at Cort and Yamaha, although they're pretty similar.
