On a, lets say hunch, I ran my VT Bass and Leeds pedals through a powered monitor instead of my amp with really nice results, so I thought I wonder how my old Line6 Bass Pod XT Live sound? Wow! what a difference! I've ran all them through my amps in the past, SVT4 pro, SVT350, ba115 and ba108 but I now realize their inherent coloring really affected the modeled sound I was getting. So for example it would sound like a Hiwatt piped through an Ampeg. I'm sure when developing their models Tech21 are listening through Studio monitors or some such thing because the difference between running through my amp/s and the full range monitor is big. So I'm now re-thinking my setup. Another plus to monitoring my setup through the full range cab is that I can D.I. to the FOH and get my sound also. And since most sound guys prefer to DI instead of mic it resolves those issues.
