Very versatile, so many modulation effects!

Very good value for money, not as all-singing, all-dancing as the Wampler Terraform or Strymon Mobius but so compact and versatile. Excellent vibrato, tremolo and harmonic tremolo, usable Uni-Vibe, good chorus, nice Leslie, and lots more. Downsides: phaser and flanger don't really match up to their analog counterparts; auto-wah, filter and harmoniser are cranky; and the controls can't hold a candle to pedals with presets - you usually need to fiddle with one or two knobs after each effect type change. But there are so many parameters you can tailor, including envelope settings, different waveforms, distortion, tone, blend and resonance that I can't really fault this little darling for the price.

Preferred Settings + Usage:

Envelope controlled harmonic tremolo is particularly nice.

Roles:

Singer Guitarist Bassist

Genres:

Electronic Rock Pop

Wish I knew about this sooner!

I am not too into modulation as a standalone effect (other than the built-in chorus on my Jazz Chorus amp), but was finding myself wishing I had a phaser here and a vibrato there. When I found this pedal and checked out some demos, I was shocked that you get so many effects in one convenient pedal (not just 11, but variations on those 11). Yes, you can use only one at a time, but that's good enough for me. If I ever want to run two, I'll just get a second Mod11 pedal.
