Hi there, i think it is hard to give any suggestions if u do not have anything in mind regarding the tone u r looking for, or the musical style or feel u r trying to achieve. Honestly there isnt a "once and for all" solution to solve ur search of the "holy grail" tone, and honestly having 2.5k may not even be enough (many guitarists have spent much much more and still not finding the sound they r after).
Perhaps u can start by thinking of any guitar heros that u may wanna emulate, check out what r the stuff (eg. amps, guitars, efx etc) they r using or other alternatives if their original gear is out of your budget.
So i guess u should first think hard on what u want to achieve and try to work around the budget u have. By doing that, u can maximize ur budget and not let it go to waste especially since this is a gift from your parents who worked hard for it. Cheers mate.
