my interpretation of devour:

verse  (bass starts at 0:33)

G|-------------------|------------------|
D|-------------------|------------------|
A|-3-3-3-------------|------------------|
E|--------3-3-3-3--5-|-5-5-5-5-5-5-5-5-/|

G|------------------|-----------------|
D|------------------|-----------------|
A|----------3-3-3-3-|-----------------|
E|-3/1-1-1----------|-5-5-5-5-5-5-5-5-|

chorus (I don't know if it's right but I play the same as the guitar)

G|-------|--------|---------|--------|
D|-------|--------|---------|--------|
A|-------|--------|---------|--------|
E|-1~~~~~|-3~~~~~~|-8~~~7~~~|-5~~~~~~|

G|-------|--------|----------|---------|
