towards the end of the video (about 4:30 or so) Jonny is holding

something over his pickup to get a feedback kinda sound. what is he using?

that' an E-Bow, didn't you know? (you could even read it, if the vid was HD)

also listen to the album version of Spies, the intro is played with slide+e-bow

in swallowed in the sea, before the whole band starts to play, you can hear it, too...

whaere else? phew, don't remember as of yet... oh, on see you soon....

 

the E-bow can be bought in most music stores with e-guitars or any bigger online music retailer.... not that cheap, but what effect is cheap? (95€ here, likely to be about 100$ in the US, for canada? no clue...)

 

how it works:

one coil, like a guitar pickup, is over the string to pick up the vibration (inductive effect...), driven into a small (tiny!) amp and put out again over a second coil. the note played will be sustained forever/till the battery runs dry. cool thing actually... with some training, you can make your guitar sound like a violin/cello (see e- BOW ;)), or a recorder etc.

the feedback-like effect is the second mode (only with the ebow plus, but they are not selling any othr ebow anymore, so you will have this), the harmonics mode. this adds - who knew? - futher harmonics, but you mostly realize the octave above or below the original note... sounds cool, eh?

whaere else? phew, don't remember as of yet... oh, on see you soon....

live version of amsterdam too.

in several, indeed!
