DigiTech Vocalist Live VL4

There’s an old saying from the days of pop music’s Tin Pan Alley that  I like to combine with a nursery rhyme and an old television  commercial: “Don’t bore us, get to the chorus.” “But when he got there,  the chorus was bare.” “What’s a mother to do?” Nine out of ten audio  surgeons recommend the VL4 for coughs due to cold, harmonically barren songs (the tenth won’t stop  playing with his long enough to comment). Oh, yeah, here’s that chorus:  “Buy the VL4 baby… Oh yeah, the VL4 you must buy… Oh buy DigiTech’s VL4 baby, read on and I’ll tell you why… Oh baybay—yeow!” (Sorry, having a Rick James moment there…; really sorry.)


Waiting for backups to arrive


The problem with previous vocal harmonizers is that they were  confused by temporary key changes and didn’t understand voice leading.  To get an effective harmony, you’d have to program each chord change as a  separate preset, string them together in song mode, and hope that you  remember to step through the sequence properly while you’re performing  (so much for giving yourself over to the emotion of the song). Even if  it worked, you looked like Mr. Ed stomping out his age on stage  (remember, he only talked to Wilbur).


The Vocalist Live’s musIQ™ technology, the brainchild and trademark  of 3dB Research Ltd., changes all that. It uses your guitar and voice  for harmonic and melodic reference, reads the two over time, and creates  appropriate harmonies on the fly—no pre-programming, no stepping  through presets, and they sound good, really good! You can, however,  create and step through your own harmonies if you choose to. I really  don’t want to take up limited space telling you about nuts and bolts  though. You can find all that out on the Musician’s Friend website.  Suffice to say you have quick and easy control over all parameters and a  healthy number of quality effects for voice and guitar. It is important  to note, however, that on the VL4,  you have balanced XLR outs, a phantom powered XLR input, and separate  level controls for lead vocals, harmonies, and guitar. This means that a  solo performer can use it as a mini PA system by simply adding a set of  powered monitors.


Cover me, I’m goin’ in


I handed the VL4 some pretty difficult tasks up front. The first was to see if it could  handle fingerpicking. I happened to notice a “CSN” preset, which I  immediately assumed stood for College of Southern Nevada… then it dawned  on me; Child Safety Network. D'oh! Not knowing either organization’s  theme song, I decided to do “Helplessly Hoping” by Crosby, Stills, and  Nash (oh,; that CSN.) Did it work? Oh, yeah! There was only one unwanted  7th that happened during the transition of the G chord to D, but I was  able to make that go away with a very minor adjustment in the picking  pattern (I had to play it right). The voicing certainly said CSN—and  that was consistent with all the presets based on signature vocal  harmonies. I also tried the famous “Nah Nah” section of Journey’s  “Lovin’, Touchin’, Squeezin’” with a number of 3- and 4-part presets. It  was like having a virtual Steve Perry singing the high harmonies. I had  a hard time deciding which I liked best—they all sounded great, but I  settled on the Gold Channel preset. Particularly disconcerting was the  Female Duet preset—after four bars I had the realization that all guys  are totally clueless, accompanied by an uncontrollable urge to watch  “When Harry Met Sally.” The VL4 also handles vibratos particularly well—natural sounding and very convincing.


Obviously live performance is the primary intention of the VL4,  however, I found it exceedingly useful as a post-production tool. Three  years ago I had arranged and recorded a song by a female  singer-songwriter who I had since lost touch with—no way to get her back  to the studio to double parts or sing backups. I sent her lead vocal  track line-in to the VL4 and played along using the normal guitar in. From there, it was balanced stereo line in to my DAW. The results were stunning.


Opposing counsel may cross-examine


Now let’s address all of your questions: Yes, it ignores fret noise.  Yes, it will harmonize with two-note power chords, but it doesn’t like  distortion. You have to connect your effects after the VL4’s  Guitar Thru output. Yes, it’s very forgiving with out-of-tune vocals  and guitars, but tune up when you can. Can you sing acapella? For a  simple section based on the last chord you played, yes, but for  complicated parts it’ll need something to read. A volume pedal connected  to the Guitar Thru output lets you mute the guitar while you sing, or  you can simply turn the Guitar Level knob down to zero. Another very  cool feature of the VL4,  for guitarists who are militant about their tone, is the fact that the  Guitar Thru is a true hardwire thru that does not affect your signal  whatsoever. (This is DigiTech we’re talking about; of course they  thought about that.)


The verdict is in


I don’t believe how good this thing is. This box is both exhilarating  and disturbing—you’ll be tempted to fire your backup singers (please  don’t, remember we can all be replaced by DJs). This machine is a  godsend for bands with one good vocalist looking for rich harmonies.  Then again, if you have a band with three or more good singers, you  should get a two-voice VL2 for lead vocal doubling and two-part harmonies, and a VL4 for each backup singer. Imagine what your cover of “Bohemian Rhapsody”  would sound like then! Performers who want to make a bigger sound than  their numbers allow will find this an indispensable and eminently  rewarding purchase. The same holds true for composers doing film,  industrials, and commercials who want vocal tracks and need to deliver  on time and under budget.


DigiTech’s Vocalist Live has taken a momentous step beyond the  expected limitations of harmony processors. There simply isn’t a better  unit. Now you can add depth and flavor to your vocal performances and  record very convincing background harmonies without numerous takes,  backup singers, and a vocal arranger. David, Steven, Graham, Neil… I’m  comin’ boys! (Sorry, Mel Brooks/The Producers moment.)
