I've had it for some months now and have had the possibility to use it with different sources (guitars, basses, synths) for different applications (amping and reamping but also to send the signal to hardware processors).
The result? It does the job. To compare it to the Radial would be comparing six of one and half a dozen of the other, but you have to admit that Radial does a better marketing job.
Finally, regarding the debate around the intrinsic utility of this type of boxes, it depends a lot on the source signal and the time you have to dedicate yourself to process it; in other words, you'll gain a considerable amount of time.
I have only used this small yellow box once this August for a reamping session for a project I'm currently working on.
I have no way to compare it to other models, since it's the first time I ever do reamping!
It has a very sturdy look (and I think it is...we'll see how it ages) and has a nice yellow color. It doesn't take up too much space on my desk.
I don't have the impression that it colors sound, it's very easy to use! You simply plug in and reamp!
A friend of mine recommended it to me and, for its price, I would surely buy it again!!!
I connect this small box to the TRS jack output of my Steinberg UR824 soundcard.
It couldn't be easier, you connect, adjust the gain if needed and start reamping,
This little metal box seems super sturdy, it comes with 4 adhesive rubber pads.
No noise nor interferences! I tested it with Engl and Hughes & Kettner tube amp heads.
