The construcctions is ok: Plastic but well put together IMHO. The expresion pedal is what we can expect of this range of prices. But it is good enough to start trying whawha and volume pedal uses.
Having the drum kit is cool to be able to play with something on the backhroud. Using the looper is going to be something dificult for a beginer but lets call it an interesting chalenge that put you at your place. It is a good way of checking how good is your tempo and it is also a good practice to get use to use that kind of tool. there are a log of more expensive loopers that required of the user to be acurate when starting and finishing the loop.
An interesting tip for users that want to use this as a desktop unit. you can change banks pushing with zour finger on the transparent button instead of the big one that is desing to be press with the foot.
My main cons on this unit is how much it colours the signal. Can you record with this, yes, becuase if when you understand how recording works, you know that your amazing guitar is going to be destroy in the process and it will lose most of the dinamic, and most of the time you will use compresors on real studios to make more controlable and easy to record. So yes, you can use it for recording, how ever I want to insists that if someone gets use to play on a device like this you will have a hard time when you change to a systems that doesn't have that compresion, becuase the touch of your instrument changes a lot. Just have that in mind. If you have an analog amp, try to practice directly in to the imput of that amp, to get good your picking tecknique and get a good reference of what are you doing on your instrument, and then you can play on this units to record, and have all the cool options that brings you.
