I'm pretty pleased with my SWR 550x, but I can't help but think that there's a better head out there for *my* sound. Maybe the skimpy EQ (3-band) contributes to my slight dissatisfaction. Since I live in a small crappy sound with no selection, I buy off eBay with no first-hand experience. I need your advice before buying. Here's what I'm trying to achieve... - NOT interested in glassy highs (not a slapper). - I like understated lows that grrrowl. - I want a pushy, punchy midrangy tone that cuts through. - 400W to 550W (@ 4 Ohms.) - Looking for a single unit. No separate pre & power amp. - Under 35 lbs. or so (probably looking for a tube/solid state hybrid) - I have two 8 Ohm cabs, so I'm probably looking for something mono. Should I try an Ampeg? What could I find on eBay? Price isn't a huge obstacle, but I'd prefer to say around the $500 I paid for my SWR used. I might be willing to pay a little more for the right head. Thanks!
