Amplitube 4 question

[Canular]

Hi guys, im been using amplitube 4 for a while now with my ibanez and my jackson. And recently i downloaded Ola englunds Mark iv rhythm preset. With the jackson sounds great but with the banez i cant get that palm muted metallic scratchy tone. ( ola englund type , metallica etc.. ) it sounds to noisy with allot bass. With other patches it sounds fine. But on this one the only one having the problem is the Ibanez. Could it be the pickups are not that hot or something? Thanks
