Some thoughts:
- Switching between the A and B presets on one 'FX Unit' is pretty tricky whilst concentrating on singing and rocking out, especially given the relative closeness of the footswitches. Using a standard pedal setup with this band, I use an OD pedal set semi-clean as my "base" tone, and stick the distortion afterwards. Rather than waste another FX Unit on the M9 for two sounds, I just had the OD on Preset A and the distortion on B on the first FX Unit, meaning I had to click a different footswitch depending on what I wanted. Sounds easier than it is.
- While the footswitches are obviously close together to allow easy access to the Scene, Tuner and Setup mode (accessible by pressing a combination of two neighbouring footswitches), me and my size 12s managed to do this a few times accidentally when I just wanted to switch off an effect. Do-able in a practise situation, but would sound pretty shit during a gig..
- The distortions definitely hold up in "real world" situations, I didn't ever feel like I was using some one-dimensional approximation of a distortion pedal, although admittedly, this wasn't really a "CHECK OUT MY JUICY TOOOONE" kind of situation. I've just used a lot of analogue dirt pedals with a variety of amps, and it fit the bill as well.
- The tuner wasn't picking up the note a few times; I'm not sure if it's down to having two pedals (Micro POG and Boss PS-5 with its buffer) before the M9 in the chain, but it definitely wasn't playing ball at times. It's also pretty fucking tiny onscreen, I'm not loving having to stoop down a little to make sure I'm aiming for the right note.
So basically, the jury is still kinda out on this one- the sounds are great on the whole and definitely cut through the mix fine, there's just a few idiosyncrasies I've got to adjust to. I'll do some further bench testing over the weekend.
