Smashing Pumpkins - With You Bass

This is another one of those '89 demos with the messed up tuning.
You have to match it to their tuning.

Riff1
G|-------------------------------|
D|----------2--2-----------------|
A|-----2-4-------------2-4-------|
E|2--2------------2--2-----0--0--|

Then there's this scale exrcise part that I'm not 100% sure of:

Riff2
G|----------------------|
D|------------5---------|
A|--4-5-7-5-7---7-5-4-5-|
E|5---------------------|

Then after playing Riff2 about thrice play:

Riff3
G|---7---------5---|
D|-----------------| right before going back to Riff1 play E(2 on D)
A|5-----0-2-3--0-3-|
E|-----------------|
