My son uses an FM9. He wants an expression pedal. I am clueless but would like to get him a nice birthday gift. Any guidance you can provide is appreciated. He plays mostly 80's rock covers. The band also writes originals but this gives you an idea what music he enjoys. He is a self proclaimed tech geek so the more buttons and options the better (hence the FM9). He has more money than me so just because he has an FM9 doesn't mean I can afford a $600 pedal
. Durability, configurability, he mentioned something about Mission having two output jacks. Anyway thanks in advance for your guidance!
