Im trying to get some serious low end cut out the highs and mids. currently im using hartke and even with the eq set for nothing but bass it still has some high end to it. my cousin uses ampeg and it sounds like crap. Do all amp makers just make amps for pop n slap or is it just me? Im thinking about using ashdown because of the "deep" button. I like the Behringer sound including the ultrabass stuff but i need something more durable since we play on stages that remind me of the blues brother movie (stage with chicken wire around it to protect the band from beer bottles).
