I play reggae w. a Peavey 410tx cab (the one w. the port in the back) and it produces massive lows. Are you playing a freakin warehouse or something?
lol, that's the cab I have now. It's just not that good; the lows get extremely muddy to the point you can't tell what the note is. And also; it's SO FREAKING HEAVY.
I'm looking for a cab with definable lows and something that won't break my back.
