I plugged my passive bass directly into my Stewart 1.2 today and the sound was incredibly beautiful. All the EQ I will ever need was in the tone knob on my bass. The volume level was almost loud enough with it turned up all the way, but not quite. I tried it into the PLX3002 next and it sounded good too, but weak. Wouldn't it be great if QSC put an instrument level input on the PLX series,(Bob)?? For many of us it would work perfectly as a stand alone amp head. No more preamps and stomp boxes and huge rack rigs. No more maze of cables hanging all over the place. A 3000 watt bass head in two rack spaces, think about it.
