Thank you all for feedback!
@Seb54, i'm sure you're not stupid at all
@Paul, i used my Eden WTDI di/pre directly into the line input of my MacBook Pro (my external soundcard is broken and will be back in a week or so... ), recorded in Logic, a bit of reverb for the solo, filmed with a Samsung Galaxy S3, edited in FinalCut Pro...and that's about it
@Zesebus, that's an RBass indeed, Bart pickups & preamp http://www.prtc.net/~rubenr/rbasses/home.html
