Hi everyone, I have a Fender Rumble 75 and it seems so "peaky" that the cabinet (or speaker?) rattles & buzzes are driving me nuts. I'm considering pulling the chassis out and building a box for it to use with one of these. http://www.seismicaudiospeakers.com/Tolex-210-Bass-Cabinet-w-Volume-Control-for-Horn-p/mb-210.htm Has anyone used these cabinets or other cabs from them? This is for use as a practice amp. I find myself using my Fender Frontman 25R Guitar amp more than the Rumble. It is flat and clean at low volume of course. Thanks for any advice.
