I have stomp boxes that I would like to put directly into the front inputs on my PreSonus AudioBox USB 96 with 1/4" cables. I've heard different things from different places. Some say it's perfectly fine, others say it could damage the preamps. If I could get a straight answer, that would be great. I know it's always good to get a DI to protect the AudioBox, but I'm just wondering what I can use before I get one. I know I can't use my acoustic electric because that's an active system. I just don't know if it's the same for pedals. Thanks!
