I hear ya, DiezelMonster. Ive had my Dual Rec since I bought it new in '94. It still blows me away with killer sounds. I think some of that is because the Rectifiers are an original recipe in some ways. They pretty much defined the bassy, growling modern metal sound. More or less, they are the benchmark for those tones.
Over the twenty years I've had mine, I've heard several other great sounding amps. However, besides my Uberschall, I havent felt compelled to purchase many. I grabbed the Uber because of its darker voicing, and would love to someday add the modded-Marshall goodness of a Bogner XTC (or possibly Helios). However, for raw aggressive metal sounds, the good ol' Dual Rec still delivers.
