Feature:
Only a loop station could make this thing better.
Quality:
Looking at the unit I thought "You get what you pay for" but after owning it for over a year now I am amazed at the ruggedness and value.
Value:
Can't beat the value this thing offers.
Desirability:
It doesn't look like much, in fact it looks cheap. But if you want to look good, go buy yourself a guitar. If you want to sound good, you won't go wrong with one of these.
Sound:
This thing is great, and the price is incredible. It is extremely versatile, if you take the time to learn the deep editing features to create your own presets you can rock the house night after night - when I'm getting dead spots I can easily add compression to whatever effect I am using and store it as a new preset - if I'm not happy with the "house" sound I can use amp modelling to fatten things up. When the house sound man says "that bass was kickin!" you'll see what I mean.
Ease of Use:
The manual is perfect. Easy to adjust to your taste.
Support:
The fact that it has worked perfectly under heavy abuse and never failed means I have never needed support, therefore top scores her too.
Overall:
A loop station is the only missing ingredient. I might upgrade to a different model just for that feature. But it will cost a whole lot more than this baby did, and it's already paid for itself ten times over.
