I use the BX3000t head and its pretty good soundwise. Especially for the money. Nice punchy sound and a lot of tone shaping capability, although it can sound hissy if you boost the treble. The ultrabass feature is useless as it doesnt track the note properly.
I also used the 2x10" BA210 speaker cab, and after 2 band practices and approximatly 10 hours total use the speaker cones split and separated from the edge of the speaker. They sounded good while they lasted and at bedroom levels I think they would have lasted a while, but they cant take much abuse. I would say 10 hours is a pretty poor show!
Buying cheap gear is false economy. I learnt this the hard way!
