After doing a lot of reading, I've realized that the "smiley face" EQ that I so love to play with has really hurt my live sound over the years. It's always sounded good to me on stage, but I never realized how little it cut through till I read some stories here. I've been playing like this for around 8 years now, and it's time to reevaluate my sound. SO, I've forced myself to set my 'Ray's 3EQ to flat, and my amp's (rumble 100, don't laugh please) EQ to flat as well, and go from there in hopes that I could 'detrain' my acquired 'smiley face ear.' The good thing about the rumble is that it has a CD in function, so I've been plugging my iPod up to it and playing with headphones to try and get a good idea of the sound without my carpeted room acoustics. My question is: Could this method provide me with a somewhat accurate view of what my bass would sound like in a live venue with a band behind me?
