Might be just a 'too much of a good thing' with all the processing and everything.
One of my favorite moments regarding this type of thing was seeing an early version of Chick Corea's Electrik Band' (not sure if I put that 'k' in the right place), with Scott Henderson on guitar. He had an effects rack the size of a fridge, and some guitar with switches and knobs all over it. All I could hear all night was what sounded like pink noise through a phase shifter or something. Al Dimeola opened the show on acoustic, and was invited on stage for the obligatory 'Spain' encore. He walked out with a Les Paul and plugged directly into a little Fender Princeton Reverb or whatever with a mic on it, and it was like GUITAR... fat, articulate... hear every note.
I'll never forget that. Same thing happened to me back in the day... I had the Alembic Pre, the Furmin parametric, the PA power amp, and when the little GK400RB came out, it blew that big rack away in a mix
