Behringer ADI21 V-Tone Acoustic Modeler Preamp and DI

Sweeten the output of your acoustic-electric guitar. A serious value, the Behringer ADI21 preamp/DI box models the warm sound of a mic on a tube amplifier.

I don't expect to need to replace it, unless it were lost or stolen.
Sound
Make my guitar sound great.
Features
I haven't had much use for the mid-frequency knob, pad switch, or ground switch. The level, blend, and equalizer knobs are pretty much set where I want them now.
Ease of Use
It took some experimentation to get the settings right.
Quality
It seems well made and durable. Only time will tell.
Value
Compared to other pre-amp/DIs, this was a good value.
The Wow Factor
If I hadn't needed a pre-amp for my passive pickup, I wouldn't have looked at it.

"Worthless Warranty"

This item was defective shortly after receiving it. Returned it to the company at my expense for repair or replacement under the warranty. 5 months later it is clear they have no intention of doing either. Others have had a similar experience. Stay away from Behringer!!

"Noisy"

Overall: 1 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I bought this hoping to add a little "richness" to the sound of my acoustic, but instead it added unwanted noise. I tried multiple cables and configurations and power sources but I was not able to eliminate the "humming" noise. It may be a defective unit, not sure. It's on my desk right now packaged to be sent back. BIG PROPS to zZounds for issuing me an RMA and paying the return shipping with no questions asked.
