hmm , well everything contributes to the how the guitar would sound in the end , i dont worry too much about amps , cause im not dragging 200 watt marshalls wherever i go but for thu guitars , depends on what sound you want , fenders are made out of alder which gives it its distinctive shape glassy sound , gibsons are usualyl made out of mahogany and the top out maple , maple is too heavy to be used for the full guitar . fenders necks have a maple base and a rosewood top , or prefebly the whole neck is maple . sharper sound thou , depend what you like , then pick ups , telecasters and strats come with single coils usually but along the way some genius thought of putting more powerful humbuckers in them , the typical fenders are still single coil based , again boils down to taste , the early gibsons had p-90 single coils in them , called soap bars , les paul juniors and melody makers still have em on , and the bfg too . most les pauls come with a more powerful humbucker and that gives it that distinctive tone . im not too sure about ibanezs cause i've never used one , neither will i ever . personal preferrence there
