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
