Re: New to forum need advice on my first Ibanez!
I'd take the 1550 over the 3550 because you're paying significantly more for a similar neck, a slightly different bridge and some horrible colours. All the 3550's have sparkly paint, that horrible mirror pickguard and multicolour pickups. The 1550 plays exactly the same, you don't have to worry about the ZPS on the bridge and the colours are more block which I prefer. Better bang for your buck, you get to chose the pickups effectively (because you're saving so much money) and you get a rebate on them at the moment.
1550 for me, largely aesthetic, but they are the same essential guitar as the 3550.
