I was browsing kijiji for a new amp recently and I stumbled across a guy who was selling his peavey transtube supreme head along with a peavey 412ms cab with sheffields in it for only $450. I really don't know that much about amps since I've only been playing on my first amp that I got when I was a beginner, so I'm not sure if I should get this. I thought that this was a really good deal but i just wanted to ask if the supreme head was any good.
