Not much to add what is said below, except:
-The power is supplied, which is rare in this price range (also works on battery)
-No on / off switch
Indeed, small, I make 48 and expression pedals is difficult grate, adding that it is very flexible ...
-The effects are not really ditables, there are nine such choruses, mas in fact we can not rgler, it's just a choice between 9 intensity chorus (same goes for delays ,...)
-We have more opportunities to rglage modulations with lla expression pedals, and it's fun, like playing with rverbe, etc ...
-There is no on / off the expression pedals, so that for example if there is a preset of wha wha, there will be all the time, and it will take a second pRSET if you do not want wha wha a passage, so the memory used and more

CHARACTERISTICS for, and given the price, I'm rather satisfied

UTILIZATION

The configuration is very simple, few connections
The edition sounds logical, but as the screen has only two digits, keep the manual for what is meant dchiffrer: Wh, wh, Bt, C1, T3, etc ...
Over time it has to come, I guess
The manual is sufficient (if needed Verify that it is in french, it exists)
Structurally, it can not be better than that so I'm happy

SOUND QUALITY

For effects there are to eat and drink ...
-The amp models are average, but it provides a varieties of saturation
Provided simulations of these speakers are fairly average, I deprecated a view Hoem-studio (can be rather fall back on the zoom g2.1u)
-The effects have little rglages, but overall there is something to have fun
Problem with short-pedals, but hey you get used to it probably
-A lot of sounds that are not garnd things (mic simulators, etc ...)
I bought it to have wha, whammy, and volume, and ca is fulfilling its role, here

OVERALL OPINION

Generally satisfactory, but do not be fooled, there is no 9chorus, etc ...
Each sound is well below the original or even a multi effects more mid-price,
it's just a draggable tite bete do everything in the bag
If this is what you need, nickel, me it suits me!
