Hi, I was just wondering whether you really do need an amp head for your bass cabinet once you have a multi efx like the l6 bass pod xt live or the boss gt 6b as a pre amp.
I'm guessing you'll be using a power amp (http://www.qscaudio.com/products/amps/plx2/) to power your cab?
The pod xt live will be able to drive a power amp but i'm not too sure about the boss...
Or you can try a zoom b2.1U... heard great things about it..
