if you are looking for a straightforward looper this is one of the best in my opinion. simple, no fancyness, no useless extra features, nice built and super easy to use, totally intuitive. the only con , for me, is it is a little too much light making you feel guilty for kicking it around, and a little nustable on marble floors or smooth surfaces, but there are rubber bondable feet to give it grip.anyway, once fitted in the pedalboard you forget about this.
more, it is true stereo, meaning that not only the input-outputs are linked in real L-R stereo, but also the loop recorded is LR (not like the DL4, for example, that has a mono looping and a stereo in-out link)
the volume knob reaches quite high volume in respect to the original sound, and this can be considered a pro, even if it has no "0db" indicator, so you have to go by ear to have the same exact level.
overall, totally worth the money.
