Hello there. I am purchasing a bass rig sometime in the very near future as a christmas gift. I am in a relatively loud sludge band. I did some research, and am now considering getting an Ampeg PF-500 head, an ampeg svt18 cab, and a big muff fuzz pedal. Is that a good rig to get for the money? (~650 dollars) Any suggestions? And most importantly, do I need 500 watts? The band has two guitarists, each with a 120 watts or so half stack. (one of them is a marshall and one of them is a 6505, if it makes any difference). They don't really turn their volume all the way up, but we play loud, and we're looking to hear the bass throughout the entire set (sludge). I'm aware that bigger is better and you can't go wrong with more watts, but money doesn't come easy and if i can achieve the same sound with a PF-350 or any other lower wattage (and price) amp, I am very interested in doing that. A big thanks in advance to anyone that's willing to give some advice.
