Im in the market for a new amp head. I mainly play 70s blues rock such as Mountain, Cactus, Humble Pie, ZZ Top etc. Im wanting a tube head *preferably under 500bucks* that will get me in that ballpark. Wattage is not a priority. I have looked into a Marshall Origin, but from what Ive saw they may not be what im searching for. Also, I do not use any pedals so I dont want anything that will require a od or distortion to sound halfway decent. Any and all suggestions are appreciated. Thanks!
