We recently acquired some JBL Eon equipment and plan to run everybody through the system in certain venues. The last couple of rehearsals I have run straight into the mixer and can really get some thump through that 18" sub but miss the tone controls of my amp. It's an Acoustic B200H. My question is, if I use the direct out of my amp do I have to have anything plugged into a speaker out jack for a load? I kinda like not lugging my cab around. Plan on buying something like a SansAmp or a Pod at some point but have to recover from the JBL purchases first.
