Hi, I'm considering purchasing a Grace Design ALiX to use with my upright, but I'm wondering if any bass guitarists out there use a Grace Design preamp with their rigs. If it works well, I would probably get a FELiX instead, as it would really simplify things on doubling gigs. I currently use a Demeter VTBP-201S with my bass guitar. I love it, but it would be so easy to just carry a FELiX around if it works well. Thanks!
