I've read a lot of negativity about ART Tube preamps, but I have no complaints personally. I needed a small portable preamp for home studio recording & this little thing does the job and more. It's extremely portable & can be used for a DI also, which is an added plus. I decided to go with this particular model for the added voicing effects & VU meter -and it did not disappoint. There's plenty of options to lock in any tone you're looking for, whether it be for vocals, guitar bass or keys. One thing I will add is that you must understand how the input/output knobs work; I read a lot of complaints about fuzz noise & hissing sounds. The trick is knowing how to dial in the output level so that the signal isn't too hot. Also, you get what you pay for -this is an entry level preamp. That being said, do not expect it to sound like a 10,000¤ Avalon preamp. If that's the quality you're hoping to achieve, then this preamp is not for you. However, if you're searching for something small, reliable and well-built, I recommend the V3 all the way!
