Like the title says, bought a new rumble 500. combo and want to order either the 410 or the 115 extention cab. I'm not realy interested in the 112 or 210. Are there advanrages to either of these cabs, or is it simple preference? I asume,that the 115, will yield more bottom end, and the 410 more presence or power. would like to hear oppinions. I prefer to keep it all fender.
