1  Welcome

If you’re reading this, you are probably a working musician or 

audio professional of some kind. You’ve spent years honing 

your craft with long, lonely hours spent strumming, picking, 

tweaking, bowing, thumping and plucking. Maybe you tour 

the world or just play the local pub. You’ve gotten up on stage 

tired, given more than you thought you had and driven home 

barely awake but your soul ablaze and still singing. You have 

friends and bandmates out there that you rely on like family. 

Some of your friends, maybe the very best ones, are made of 

wood, steel, glue, bone and strings. And now you can welcome 

Felix 2 to the latter category. 
Regardless of where and how and why you play, from here on 

out when you look down at that stage floor, it will be down 

there shining back up at you, making you sound better and 

your job easier.
While this is not the most complicated piece of gear you’ve 

ever operated, it does come with a great deal of flexibility and 

setup options, which means we highly recommend you have 

a good look at this owner’s manual to familiarize yourself with 

the finer points. Once you overcome the learning curve (easy, 

we promise), you’ll find Felix 2 to be intuitive, powerful and 

really quite user friendly.
Most of all, we made this preamp so you can make great music. 

So read this manual and then get back to work!
