"Simply the Best for Less $$$$"

Overall: 5 out of 5 stars
(see rating details)
Even though I have an AG-30, from which this circuit was taken, I am ordering the DI to have the tone control/shaping ability that fits in my guitar case. However, the AG-30 is a great deal. For $70 more than the DI, it has the DI plus an amp and speaker that work great in their own right and can serve as a stage monitor if you're connecting to a PA.
Sound
Actually, I have the AG-30 amp which includes this DI. If you check out the Ultrasound site, they describe the DI as an AG-30 without the amp and speaker. If you run K&K pickups the 1Meg Ohm input of this DI is a perfect fit.
Features
XLR out, Line out, guitar out (for a tuner), EFX loop, phantom power capable, it's got it all.
Ease of Use
Very easy and intuitive to use. The shape control takes some experimenting but overall it is simple to use.
Quality
Heavy steel case. Looks great. Should last forever.
Value
No Preamp - DI comes close to this price point for the features...
Manufacturer Support
I have emailed Ultrasound at least a dozen times and they are always responsive and detailed in their answers.
The Wow Factor
It really is a God-send to acoustic guitarists who employ K&K pickups. Of course it works with any piezo pickup and the shape control helps sqaush the quack of UST pickups.

"Awesome DI, essential for live performance"

Overall: 5 out of 5 stars

Been playing for 20 years, would not gig without this
Sound
Does it's job as a DI, also has basic EQ, sounds great
Features
This thing is the most versatile DI I've ever used. Lots of wiring solutions, multiple outs, effects loop, volume pots on every output, awesome
Ease of Use
No instructions necessary, very simple to use...however, note that if you aren't going to use phantom power or a 9v battery, the DC input is a 2.1 mm tip POSITIVE (if you daisy chain it with the power from most other footpedals, you'll need a polarity switcher, as most pedals are tip negative).
Quality
Had it for about 3 or 4 years, in constant use every week, never a problem
Value
I wish i had this thing for all the years i'd been playing prior to buying it...
Manufacturer Support
don't know, never had to use them
The Wow Factor
This is a dumb question..."sex appeal"? Really? It's a direct box, folks, it's a black brick with some knobs on it...HIGHLY practical though, a must have for any live gigging musician
