I got this in poor condition, and somebody hadn't even biased the tubes. I had it hot-rodded. Not sure exactly what the guy did, but with the main volume on about 3, and the Master on 2, you get the nice clean sound Fender is known for. However, with the Master Volume on 1 and the main on 10, you get a nice crunchy overdriven sound.
This is my primary amp and I absolutely love it... Buut It weighs close to 90lbs, mainly because I have JBL D120-F speakers in it. It gets the pure clean tone that I absolutely love!
