Bill Kelliher

For his two-amp lineup, Kelliher went with a ’80s Marshall JCM800 and a Marshall Kerry King 2203KFK JCM800, the latter of which has KT88 tubes that crank out “a chunkier, fatter, heavier sound than the standard JCM800.” The heads blast through two Mills Acoustics 4x12s loaded with Celestion Vintage 30s and a Marshall 4x12 equipped with 75-watt Celestions.

Amp wise, I was using a Laney VH100R for awhile a two channel thing in combo with a JCM800 dual channel.

In this video Bill talks about his rig and this amp.

Bill Kelliher’s guitar playing is rooted in metal, infused with rock 'n' roll, progressive rock and sprinkled with bits and pieces of thrash, punk, and psychedelic-ness. So, when it came time for Mastodon’s guitar player to design the ultimate amp to cover the complexity of his playing, Bill decided to team with long time friend and respected tone guru, Dave Friedman.

In this video (around 3:08), Bill says, that he uses Fender Super Reverb.

“Finally a tube tester that I can test all those pesky old tubes lying around the house. I found the orange tube tester a sight for sore eyes, very easy to use and quite easy to comprehend and incorporate in the testing of all the tubes in my amp giving me a value to each and able to match tubes for best performance in a nice small package.”

At 6:23 of this video, he mentions that on some nights instead of his Marshall JCM800’s he would use a Blackstar HT Metal. “Other nights I’ve been using a Blackstar, I think it’s the HT Metal head, which I love for the natural distortion and the clean on it sounds great”.
