Here's another question: is there any way that I can get in direct contact with Line 6 technical support via email, rather than posting something in a forum like this and hoping that it gets answered? I seem to find myself navigating back into the forums everytime I click on something support related, and it's a little frustrating.

I would just like to offer a bit more clarification to the original question that I posted: my stereo amplifier appears to have converted itself into a mono amplifier. Whether this has been brought on by user error or a breakdown in the product's components is not that important: I would like to sort this issue out, and I just want to make sure that I haven't overlooked something obvious (such as, for example, something in the system setup) before I shell out for shipping and repair costs.

Any help would be much appreciated... thanks in advance!

Roger that, and will do. Thanks for the advice!
