Upon comparing my sound through nicer headphones to my sound through my practice amp, I've come to the conclusion that my 25w Peavey Microbass practice amp is no longer cutting it. I need a new combo amp that can fill a small hall/garage properly; perhaps in the 100w range or so. I know almost nothing about amplification at this point. I'm not looking to spend more than 4-6 hundred dollars. I enjoy the muted, midrange to high playing of jaco or rocco prestia, but I'd like an amp that could also supply some serious low end growl, something my peavey is sorely lacking in. Any suggestions?
