I've owned a fender rumble 350 combo for many years. I play classic to punk rock. Played many venues- small medium clubs and outdoor. Always been happy with the tone- warm, punchy low end without being muddy. The tone though diminishes noticeably within about 10-20 feet from the amp, even at higher volume. It's still loud enough to be heard but less low end, and harder to cut through the mix. I figured I needed to switch to a newer combo with more power. Tried out the Rumble 500 & Ampeg PF 500 side by side with my Rumble 350. My 350 was better than both of them- tone and volume. Even the store GC salesman agreed. So if I still want to push the tone/low end out more and cut thru the mix, do I need to switch to a separate amp 500+ watts with a 410 cab? I'm also considering the GK MB212 ii combo but worried it might have the same vintage rock n roll low end I like. Maybe I should just keep the 350 and run it through the PA? Any thoughts?
