Slow Decay Guitar tab

ok. i figured it out in like the last 5 seconds. so this is only the first part. its a
step down, in drop D. on bass. this is a very rushed tab. i am sorry for mistakes.
and tell me about them, then i will get back to you.
i managed to tab the easy part =D. here it is:

The fingering for the first part is a simple Em.

Eb:--------------------------------------------------------|
Bb:--------------------------------------------------------|
Gb:--------------------------------------------------------|
Db:2-2--2-2-2-2--2-2---------------------------------------|
Ab:------------------2-2-----------------------------------|
Db:---------------------5-5--2-2--0-0-2-0------------------|

then the intro for the guitar (with a slight palm mute)
