I've been doing some searching and its come down to the two listed above. The rumble 500 and the hartke hd500. They both get outstanding reviews, and they're both what I'm looking for. Powerful, lightweight, great tone, and gig worthy. They're identical in price. They both peak at 500w, though the Hartke has an RMS rating at 250w and the Fender at 350w. I know that wattage doesn't always translate into volume, but 250w is a definitely a tad concerning. I don't want to blow out the speaker by pushing it beyond the RMS rating, and gigging regularly I feel I might be, but I'm not sure as I've never been able to push the amp myself. Thoughts? What would you prefer? What would you say is a better product?
