I'm looking for a versatile rackmount multi effect that works with bass. I love the Lexicon Reverbs and delays, but the racks don't have an auto-wah/envelope filter, this is my favorite bass effect (for R & B, Pop) The TC units sound digital and fake to me, but they have a funky preset that doesn't sound bad and would give me that autowah sound. The Boss GT Pro unit is designed for Guitar but has tons of effects. I'd love something with XLR ins/outs for running vocals through the Reverbs. But I imagine that's asking a lot. I play all styles of music with Guitar and Bass. So basically: Good sounding Reverbs for vocals, guitar and bass. AutoWah for bass. Guitar effects a bonus. I have a PA/mixer, and also a Sansamp RBI. I have a Showman for guitar.
