Hi all, I have noticed that you can pick up an 8 track powered mixer for a whole lot less than a dedicated bass head. Can someone please explain why. Would it be a good idea to use one as my amp, rather than fork out large sums of cash on a dedicated head? It gives so much more in the way of tone shaping as well as gives the option to run other instrumentsinto it as there are efectily 3 outputs vis: speaker L & R as well as monitor, which is driven by a separate amp. Comments please.
