I bought the markbass micromark to practice at home, a job this little amp is excellent at. I have also carried it to friends which of course was no problems at all.
Personally I like to have options in my gear, for alot of people the plug in and play style of the micromark is desirable but for me it is a definite downside, there is simply not all that much to do on the amp if you dont like the sound your getting. The sound is good for such a samll amp though, the low frequencies are amazing. But again, there is no way to actually alter the sound and I read in a review above that it dosent colour the sound, in my ears that is simply not true at all.
The quality leaves no room for critique, sturdy as hell.
All in all the amp does exactly what i bought it for. In retrospection I do think I may have paid a bit to much for the purpose though.
