Dronebox Demo video from Oli Larkin on Vimeo.
"This is a quick demo of dronebox being used to process electric guitar. In the video i turn on one comb filter, change the pitch and then turn on four comb filters which are tuned to the notes D,F and A (d minor chord). When i play one of these notes on the guitar the corresponding comb filter will resonate. For more info see olilarkin.co.uk" follow-up to this post.
