1 Welcome

Like its big brother FELiX, the ALiX you hold in your hand is
designed to make you sound better, play better and have more
fun in the process. From Banjo, bass to bouzouki, if it has strings
and a pickup, ALiX will make its tone shine through.

While ALiX is not the most complicated piece of gear you’ve
ever operated, it does aord a good bit of exibility and setup
options, which means we highly recommend you have a good
look at this owner’s manual to familiarize yourself with its
ner points. Once you overcome the learning curve (easy, we
promise), you’ll nd AliX to be intuitive and user friendly.
