Trs really easy to use. The record is truly incidental ... Same for beginners.


Bank of effects rather complte.
INTERESTED amp simulation.


Take the Korg A4 for what it is ... A camera amateur. So in this CATEGORY is a great device. Trs easy to use and easy to carry and connect. Solid. It possde a range of effects complte enough to really have fun. And there is room to record your own sounds! ...

You can not make a prtendre begins CF career was with the feet, of course. But for guitarists who want to work and have fun at home or in group, IDAL. Especially given the price at which it is found today. For beginners in the world of multi-effects, it is a good working basis TRS, which has nothing to envy some current devices of the same type. The sumulations amps offer a range of sounds INTERESTED ... Personally, I used the A4 scne on long enough for a directory of occasions, nickel c'tait! It allowed me to learn and understand the sound before I turn to things "prcises" for the sound I wanted ... Things more analog oldest ...... And more expensive!

cfr previous opinion


In my memory, use was intuitive.
Nothing special to say except that the effect pitch / shifter set so drop tuning was not usable because of latency.


It was time for a good multi-effect, but the amp simulation had not seemed convincing.


I bought this multi-purpose there are over 15 years. Resold a few years later. It was not bad at all for the time, but is now completely outdated. What makes me bring him a low rating.

If you find a used one, do not bother to pay dearly ...
