As I indicated in the description of the KB-50, there was little respect for the consumer. Do you get a good sound? Well, yes, from the time when we move from internal speakers to a keyboard amp. Put in 2, you will have a stro. on the other hand, no group too small because its power except in the absence of a battery. On occasion, this does not rate very dear ... This simple and friendly ACCS earned him a point higher than the Laney KB-50.

The report qualitprix n'tait era of means (F 1600 I think), but now it must be more interesting. It may be wise to make this choice especially if a gure of money and space ... But otherwise, you get no sound heavenly ... Yes, I have tested and compared to other amps keyboard. WARNING!
