I think in the short-term, I'm going to see if my little Mustang I amp can be run into the house using the headphone out -- mostly a matter of getting the right cables and adapters for it. While thinking about this, I realized that the HD400 I used on Tuesday was the first modern-day full modeler I've used at a church. When you use those digital models, it's a bit different from using 'quasi-modelers' like the GT2 or Tech21 TM60, in that each of the digital models seems to behave very differently from each other.
