Upon closer inspection of a romFX, I have come to the conclusion that we are dealing with apples and oranges. At first I thought the rom was just a sound board that you hook up to an amp, but now I know that it is an amp like mine, only it converts the sound into digital output. Mine is anolog. So, there is no mixing and modding; you use one or the other.
My Bommar rocks for sound, but it's just not the same type of sound as the romFX. It just looks better and comes finnished with built in fans.
I'd like to get my hands on a romFX so I can build a box for it. I could make it look like my Bommar. So far the only setups I've seen look jerry rigged with wires, tape and hot glue.
I'm vac forming parts this weekend. Wish me luck.
