MXR M107 Phase 100 : moosers's user review
The MXR M107 Phase 100 is a phaser pedal that is designed for use with electric guitar. It was kind of supposed to be the next step up to the MXR Phase 90 with more options, although I'll say right off the bat that I don't think it's best sound is as good as the best sound on the Phase 90, although the 90 is of course simpler. The Phase 100 has 1/4" connections for input and output and can be powered with a 9 volt power supply. It's not rackable since it's a foot pedal.
The configuration of the MXR M107 Phase 100 isn't too difficult to understand. The first parameter is for intensity and the second is speed. Intensity has four waveforms to choose from while the speed has two. That's pretty much all you need to know, which is more than the Phase 90, where all you need to know is speed. If you want to know what each waveform for intensity is exactly, it probably has that information in a manual but I haven't seen it so I'm not sure.
While I do like the overall sound of the MXR M107 Phase 100 and do think it's more versatile than the Phase 90, I still can't say that I like it better overall as a phaser pedal. It seems only logical to compare this to the Phase 90, but setting this aside for a minute, the Phase 100 is a very solid sounding phaser that is capable of getting a wide array of different sounds. It's got 10 stages and makes for a cool collection of sounds between the different waveforms.
The MXR M107 Phase 100 is still being made today, although there is a vintage version with the script writing as well. I've only used this more modern version of the pedal and think it's pretty awesome to have around. I still wouldn't recommend going alone without the Phase 90, but having the Phase 100 and Phase 90 pretty much covers all the bases when it comes to phasing effects. Check out both of em first to be sure which one you want if you can only get one, but these are pretty much the way to go for phasers.
