I was just at a music store in Atlanta checking out amps. I ran a Fender custom shop strat through a Hiwatt Custom 50 head and Hiwatt 4X12 cab. Just for gits and shiggles I cranked everything all the way to 11 and I thought it wasn't plugged in. Not even the slightest hum. F'n amazing! So, are there any other amps as clean as this? What's the cleanest amp you've played?
