the blue box is so nasty that I love it..It's mechanical! I play it even with a moog sinth and it could be cool but you have to be carefull with freq cause it could dont sound at all
....I like to play it just with the 'blend' pot completely closed and sink it into an echo or let it circle into a sweet phasing or flanger (interesting in stereo) but it's definitely great at a quite loud volume for me. Good even to stoned any drum rhythms....
