Sometimes you’ve just got to bring out the epic sounds. I use the EHX Bass Micro Synth all the time, and it’s even more massive when combined with the Darkglass B7K. This one’s mostly improvised, but I kept coming back to that main lick, based around a simple natural minor progression. The trick here is to ‘shake’, i.e. rapidly slide the fretting finger between frets.
Enjoy, and don’t forget to download the transcription and backing track.
