Hi there,
As I don't own 12 string I can't get this exactly right but I believe it's one of
three things (or a combination):
(A) Capo on 3rd Fret
--2---2---2-------0-----------------------------|----3-------3-------3---------------------------|--------------------------0-2---0-2-------2-----|------------------------0-----0-----0-------4-0-|2-------2-----0-4-----0---------------0-4-------|------------------------------------------------|
(B) Capo on 3rd Fret
--2---2---2-------0-------6-8--6-8--------8-5---|----3-------3-------3-------------------------6-|------------------------------------------------|------------------------0-----0-----0-----------|2-------2-----0-4-----0---------------0-4-------|------------------------------------------------|
(C) Capo on 3rd Fret (probably right)
--2---2---2-------0---------5-----5------8--5----|----3-------3-------3-----8-----8-------------6--|-------------------------------------------------|------------------------0-----0-----0------------|2-------2-----0-4-----0---------------0-4--------|-------------------------------------------------|
I think the effect is slight vibrato (on a pedal) and that's it.
Cheers,
Raj
