Seems a somewhat extreme reaction! The majority of reviews I have read have been positive and clips I have listened to suggest a good sound. I certainly felt that when I tried it out.
What don't you like about them? Have you tried one?
Back to the topic of the thread.
I had wondered about the Roland Micro Cube bass. I shall take a look at that and also the Line6 and Pignose.
At the moment I plug it into my Marshall MS4 micro amp. Obviously it doesn't give the full bass response but it was better than I expected and it just gives enough boost for practising at home.
