Hey all. I know a lot about different brands, but I need some feedback on what works well. Where else could I go for good honest feedback, tests, experience, and actual product research! I want to get a new head for my Ampeg SVT-410HLF. Ideally, I'd like to match it with an Ampeg head. But I'm not limiting myself. I'm currently running it with a Hartke LH1000. I love the head, but it's just not cutting it for me anymore. The bottom is boomy, and I cant quite get a GREAT sound with the LH1000. So here are the heads I'm considering: Ampeg SVT-4 - Big massive monster. Ampeg SVT-7 - I love the tone. But I'm nervous of the quality and reliability. I've heard the stories... Gallien Krueger 700RB - I've heard these sound incredible paired with the 410HLF Gallien Krueger 1001 Gallien Krueger MB800 - Small, powerful, but I've heard it lacks balls. Hollow sounding? Aguilar Tone Hammer 500 - I like these, and I love Aggies, but is it enough power, and is it rackable? I really need headroom. I'm in a wedding band, and I usually have support, but not ALL the time. I need something that will really give me great tone if I'm direct out of it, and I need great tone from the amp itself. Any suggestions? Rack mountable is pretty key as well! Also, if you think of any other GREAT heads I didn't mention, suggest away.
