I had a 5153 for a few years, and recently sold it, and ended up with an Archon 25 combo. I swapped the G12t75 for an EVH greenback, and that made the amp a million times better. The Archon is very different from the 5153. There is zero buzz, it is a darker, and fatter amp in general, but somehow at the same time it has way more note definition. With the Archon I find I have to run the gain high to get the sound I want, and work the volume control if I want less gain. Also the Archon clean is one of the best I have ever played.
