The first thing I'd like to do is apologize in advance for my ignorance on this subject, but I guess that's why God gave us forums... Okay, here's my question....I currently have a Walkabout Scout combo unit..great amp, great sound, lightweight, perfect. The Scout is great for small venues, but I'm afraid the 300 watts isn't going to be enough for large venues. I always DI my bass, but I also like a lot of stage volume. Is it possible to hook up an external power amp (like a Mackie 1400, etc.) and use the Walkabout as the pre-amp for this unit? And if so, how do I do it? I'm trying to drive a couple of Eden 410XLT's (4 ohms each). Suggestions and/or advice will greatly be appreciated. Thanks!!
