I'm very close to taking the plunge on this. I would really like to hear from those of you who have incorporated it into your live gigging and how you have approached it on stage so that you can focus on playing and not on messing with the pedal very much. I've seen lots of videos, read all the threads I could find here at TDPRI and elsewhere. I really like the iOS based interface-- seems really slick, making it a lot easier to edit presets and also set up the pedal the way you like it. I really like the fact that this should be able to handle just about every effect except dirt: reverb/delay/modulation/chorus/phaser/univibe/leslie/tremolo/autowah:wah. I also realize they have a lot of custom algorithms that create very unique sounds, although they often could use a bit of rolling off the extremes for more practical use in anything other than an ethereal sort of band. The MAX is costly but when you are essentially getting dozens of pedals in one with no limit it seems pretty amazing. I'm thinking of getting the MAX as well as an expression pedal and seeing how well that works for me to start. I would be also using my OD3, maybe TU-2 (although the H9 has a tuner), and that's about it. Possibly a boost pedal in the front just for when I use weaker single coil guitars. I play in a funk band and generally play pretty clean. I don't use effects much at all, but it would be fun to spice things up here and there....though $700+ is admittedly a bit expensive for a little fun. What I really like is it seems like something really easy to program, mainly due to the iOS control interface. Sounds like it should be easy to hone in on maybe 10 very useful, giggable sounds and then set them up as the available presets for the show. I also like the fact that the sound quality is stellar. I don't care how cool it is and how many effects there are if they sound too digital and fake. My biggest worry is how giggable it will be. I think I will be OK. My approach will be to have one effect that I am interested in using in a song, that's it for starters. So before the song I can set the pedal up to be ready to play that effect. That way, at least for now, I can just toggle it ON or OFF: I don't need to worry about it being cumbersome to switch to a different pre-set in the middle of a song. I know there are a few options for making switching among presets on stage mid-song more feasible: - setting up the tap tempo switch to change pre-sets....although then I guess you lose the ability to use it for tap tempo. - using dedicated, programmed aux switches and setting them to go up and down between pre-sets. Then there's a little complication on how to hook those up along with expression pedal using adaptors for TRS jack. - maybe having the iPAD on a stand on stage and using that to toggle from pre-set to preset if that is ergonomic and not too dorky. - buy another Eventide Core unit and then I can easily set up two effects good to go for each song. This seems a bit more expensive way to go, obviously, than trying to use aux switches and a single H9. The other key contender in my mind was the new Boss MS-3. I could have my favorite dirt pedals in the provided loops, and mainly use the Boss's built in effects for time-based and modulation effects. It might actually be easier to string together multiple effects and then toggle them on and off since more switches are provided and you can set it up so the switches toggle on and off the effects you've set in the line. On the other hand, the programming interface is likely a bit more difficult. It is a lot cheaper, but the sounds by all reports are not as high quality. I am aware that in theory the H9 only allows one effect at a time. But many of the effects actually combine mod+reverb+delay so that's not really an issue. Plus, I can use amp reverb and my Carbon Copy delay on my board if I really feel it's necessary. I generally find using one time-based effect at a time is often a good way to go, anyway, to keep things from getting too muddy. And/or tweaking the H9 pre-sets to create nice-sounding effects that have several things going on but still cut through.
