Thanks for this opportunity, ... was fun and learned a lot in the process. Looking forward to John's magic touch.
I have only a flanger on the congas in terms of modulation effects. If you are referring to the rhythm guitar, I have changed it from a 6-string to 12-string tuning to add fullness. To do this, I transposed a duplicate track with 12 semi-tones and added a LPF to cap the B & E strings to B4 & E4 respectively.
