Presets are pretty useless for actually performing.

Programming is limited (you can only control about 1 param for each effect altho there are sometime 10 graduations of the basic effect).

Noise is the real issue. Hiss and more hiss, and if you use any of the distortion/overdrive stuff, you'll absolutely need to use the built in noise gate feature and when you quit playing you'll hear this LOUD hiss trail which gets clamped by the noise gate. But it's just not something you want to use for music you care about.

Even the built in tuner is kinda hard to see standing up.

I usually like Alesis effects, I think they usually have some of the best DSP algorithms out there and usually Alesis is king of the low end. But this time they missed.

This is a decent pedal, if you can learn how to work it correct. I mean I must have spent a week or two trying to figure out how to work this thing. So I suggest that you take youy money and purchase a different brand.

When I was considering the purchase of a new multiFX unit to replace my aging DOD Acoustic1 unit, I selected this because on paper it seemed to have the most bang for the buck compared to comparably priced units made by Behringer, Zoom and Digitech. I downloaded the manuals from each manufacturer's website and read all the previous reviews. Nothing prepared me for the nightmare this has been. The factory presets are substandard. The instructions for editing and storing settings do not work. And customer service at Alesis is non-existent when trying to resolve the issue. Alesis has been aware of the problems for over two years and has made no effort to either redesign the unit or rewrite the manual. I do not ever plan to purchase a product bearing the "Alesis" name again.

At least it works! Some of it's sounds are okay for just banging around on my Strat for fun, but that seems to be about it. I got this as an open box item, reduced, but I'm disappointed in it, mainly because of the noise--way too much hiss. Also it is difficult (for me, anyway) to change or create settings--frustratingly complex--and the manual is mostly geek to me.

Overall, the range of effects is good on this unit, but it is so noisy. The hiss will just drive ya nuts. Additionally, we do one song that has to switch from the wah affect to overdrive with no chance to hit the volume knob on your guitar and the volume difference was agonizing, with no way to adjust it.
