wiiiiie, I'll get my bass this week

All 4 fingers, i dont see the pinky being used, he does slap bass in some parts, its very dynamic the way he plays, but plays it in the standard proffesional way, post a picture of your bass. The bass guitar on By Your Bedside is way different than the guitar parts.
 
yeah, I used Guitar pro to take the bass out and found it imposseble to play it using only the index and middle finger, atleast when your new into bass...
The bass is just a regular Ibanez GSR200...I liked the sound compared to the price and so on...
