Feature:
I love the similicity of the controls, I set my amp (GK 400RB) and change the sound using the Aphex. The range of control available on the DI is excellent. The ability to take any power adapter is great, but actually the unit uses so little power I really haven't needed it.

Value:
It is expensive, but it does do the job.

Desirability:
Simple gear that does what it says it does. Not over engineered, not goofy.

Sound:
The sound is very easy to dial up, what I like is the sound is fuller but it doesn't drive the pre-amp, in fact it appears to have very little effect on the gain at all, a small miracle. I think what you get is a clean, full bass sound. When I DI it to the PA people come up to me afterwards and tell me how good the bass sounds, that has never happened to me before.

Support:
So far no need for support

Overall:
This little box has made a huge impact on me being able to dial up my sound. I am very pleased I got it

Feature:
Power circuit lets you use almost any AC adapter you can throw at it -- Boss, Ibanez, etc. so you can use whatever is hanging around in your closet or gear bag. That's a good design. Simple to use knobs, clear markings, and all. At first, the manual seemed slim and I wanted more details, but after playing with the pedal, I realized the sound is what it's about, and that's easy to get to.

Quality:
Seems sturdy enough. Using it for once a week gigs, where keep it velcro'd to the top of my amp. So far, so good. Never crapped out, always works as expected.

Value:
Was looking at expensive multi-fx pedals and chose this because, while it did less, it sounded better. So I guess I saved $150 that way...

Desirability:
Kind of hard to get excited about it without trying it. Graphics are a little wild, like those Toyota interiors that are supposed to appeal to young drivers. But hey, once you plug it in, it's very easy to live with.

Sound:
I was looking for something that would improve my live sound, but wasn't sure what I needed. This pedal impressed me in the store when I plugged it into a Crate and got it to sound like a fine Ampeg. On my own rig, I've been impressed by the emphasis and clarity it provides, and helps me really expand my sound. I'm in a duo, and this really helps my bass fill in space. Defintely makes a good setup sound better.

Support:
Never needed them

Overall:
Like I said, I didn't know what I wanted to improve my sound, but I am amazed at what this pedal does for me. I can't imagine anything having as much impact, for even double or triple the money, so this one has earned a place in my gig bag.
