Sound — 10
Right now I'm running my ESP Ltd F-50 to my M-116 and then through a Fender Vintage Volume pedal to my 15 watt Line 6 Spider IV, and I had a lot of trouble getting the tone dialed in on it, but now its exactly what I wanted. Its not very noisy unless you have the noise gate turned off. I was able to get a great Avenged Sevenfold tone out of this pedal once I figured out the right settings on my amp.
Overall Impression — 10
I mostly play heavy metal, thrash, and speed metal, so this was the perfect pedal for me. When I first saw it in my Musician's Friend catalog, I thought I actually heard a choir of angels singing somewhere distant, I'm not kidding! This thing is amazing for all types of metal players! I've been playing electric for about a year and a half and this is the sound I've been looking for during that year and a half. If my M-116 was stolen, I would track down whoever stole it, beat them with a bat, and take my pedal back. Or just buy another one. There really isn't anything that I think this pedal needs. The best thing about it would be how much you can customize your sound on it. You've got a bass knob, mid knob, treble knob, master volume, gain knob, mid frequency knob(adjusts what frequencies the mid knob affects), and you've got a noise gate button and a scoop button. A bad thing is I haven't been able to get a good tone out of it with the Scoop activated.
Reliability & Durability — 8
Even though I've only had the M-116 for a month, I've already managed to bash it into a couple walls and doors, and it had absolutely no effect on the pedal. The thing's made out of what I think is 1/8" solid steel, and it is extremely rugged. The only thing that I would want for it during a gig would be spare batteries in case the ones that're in it right now die. Which reminds me, this thing eats 9v batteries like nothing else, so you're better off just getting the power adapter.
Ease of Use — 7
The M-116 is pretty easy to use and takes very little time to get an amazing sound out of it. I never read the manual, I just started twisting knobs, and I had it dialed in after about 10 minutes on my pos Fender SP-10. My Line 6 Spider IV, was a completely different story. I've had the pedal since Christmas, and I just got the Killer tone I was looking for to come out of my Spider IV. It was worth the work though.
