 think it was it was kind of constant we were able to really hone in on the guitar sounds i think for can't get enough of it the kind of general guitar riff that i play was eventually played through four different vox amplifiers that we linked together simultaneously with the tremolo pedal just to get that perfect time and i think we went over and over until dan fox himself came in and was tweaking the pedal to get it to be exactly in time with jack strumming because we couldn't have them off
