I currently have a hartke 3500 head and a Hartke 4x10xl cab using a older Ibanez proline 4 string playing godsmack style music. My problem is that my guitarist purchased a Mesa boogie single recto verb head and a 4 x12 mesa boogie cabinet with ev's in it and no matter how I set the eq on my amp or what volume level I am at or the guitarist levels are set I seamed to be drowned out. The guitarist is unwilling to change his setting because they are set to how he likes them. So I am possibly lookign at a differant and speakers. I would like to stick with a 4 x 10 cab. I was lookign at a SWR Goliath III and maybe a the 350 or 500 series head. Has anyone run into this problem or has any suggestions?
