["This is my main pedal for modulation effects. It replicates an arsenal of chorus, phaser, and tremolo effects very nicely. I've used the tri-chorus setting on a number of tracks I've recorded with the Mayfield Four and Alter Bridge."](http://www.premierguitar.com/articles/20392-mark-tremontis-top-5-amps-and-myles-kennedys-top-5-pedals?page=3)more
This photo taken by Graeme Flegenheimer of Buckethead and his pedalboard reveals Buckethead uses a Line 6 MM4 Modulation Guitar Effects Pedal (it's the blue pedal, second from the right in the string of pedals pictured). This photo is from a May 28, 2009 show at [Higher Ground](http://www.highergroundmusic.com/) in Burlington‚ VT.more
This image comes from [this article from *Pro Guitar Shop*](http://proguitarshop.com/andyscorner/prince-the-unsung-guitar-hero) where they write "Along with his love of Boss effects, Prince is a regular user of the [Digitech Whammy](http://equipboard.com/items/digitech-whammy-pitch-shifting-guitar-effects-pedal), [Dunlop Crybaby Wah](http://equipboard.com/items/dunlop-gcb95-cry-baby-wah-wah) (though he has been known to use a Colorsound Wah as well), and Line 6 MM4 modulation modeler."more
"All of Mason’s clean boost and dirt pedals are on a no-name loop box that Mason bought “from a dude on eBay.” On a separate loop station, Mason runs his more trippy effects, starting with an Electro-Harmonix Stereo Memory Man and a Pigtronix Tremvelope. Next in line are Wampler Faux Tape Echo and Faux Spring Reverb stompboxes. The final effect is an old, tried-and-true Line 6 MM4 Modulation Modeler."more
I don't use modulation effects often enough to justify having individual pedals for everything, but I still want to be able to use phaser, tremolo, and flanger when I want them, so this pedal took care of those needs. It's not perfect, and the effects aren't amazing sounding, but they do the job well enough.
Pros and couns awesome. Nice simulator as every single Line6 products, but these series FM4-MM4-DL4- has a problem, the drop volume when used in line with other pedals. But, you can solve these dramas making a lil upgrade mod to became TBP and adding an extra patch. The pedal will become an indispensable tool for you sound, truste me! The boring thing is that you can´t mix the fxs per bank, you can´t blend chorus with phaser and else....
I used to have many modulation stompboxes before buying the MM4: Ibanez CS9 Stereo Chorus, Dunlop Univibe, Boss TR-2 Tremolo and MXR Phase 90. They all sound awesome, but they're too many. The MM4 is a great piece of gear that gets the job done.
Great! Some of the effects do have a volume drop, but I compensate by eq'ing from the bass. Great phasers, leslie rotary speaker, I use the panning with my bass and 2 powered speakers.
