So, last week my Valve Senior head blew a tube. It started going all crazy and shooting sparks and stuff and then just completely shut off. I took it to my local music shop and they told me that I had blown my Power Transformer. What the hell. So I called up Gibson and bitched at them for a few hours and now they're sending me a brand new one, heh heh. Here's a pic for those who don't know what a Valve Senior is:
All in all. Gibson's customer service is pretty dang nice.
