If you haven't got so much money and if you are producing without using so much Vocals, then it is a Perfect Mic and Recorder even for Vocals. Very Nice for the price! 5 Stars! Also buy the Accessory Pack, you'll need it!
I recently exchanged, at Guitar Center, a crap Tascam DR-40 Linear PCM Recorder for this Zoom device.
The Tascam had two issues, the main one being it was set for Auto Record and pausing after 5 seconds of recording. I could not stop it from being locked into Auto Record and every single time I tried to record something, it repeatedly paused after exactly 5 seconds. I read online that this is a bug or glitch that is common with it.
The other issue was this: to register the Tascam DR-40 you have to enter the serial number, which is supposed to be on the bottom panel. Nope. No numbers or text is imprinted on the bottom panel. I had to look at the box and guess which number was the serial number (it's 7 digits and starts with 0 or 00). No serial number on the device itself? Very incompetent.
I've had the Zoom one day and I used it to record my jamming on a new Kaossilator Pro Plus, MicroKorg, and MicroBrute, with wild sound fluctuations and changing levels. The Zoom handled it fine and dandy and recorded the entire hour long session.
I exported the WAV files from the SD card into my Sony Acid DAW and the recording seems absolutely perfect in every way.
Had one model or another for 15+ years. Field recording, sample grabber. Also handy for other uses that lend themselves to anything where portable & easy are key.
Best of all I carry it in my pocket without a thought.
Always be recording.
