The newest bassist of Slipknot, Alessandro "Alex" "V-Man" Venturella posted this photo on his official instagram of his rig. The bottom 3 racks are all Gallien Krueger heads and the top head is a GK Fusion 550's. He goes on to make a joke about recruiting one of Mastodon's guitar techs. Alex himself teched for many bands including Mastodon.more
Seriously. If you can find the tone you are looking for on bass with this amp, you're doing it all wrong. The tube front-end gives you warmth and the solid state back-end provides punch! This amp is extremely versatile; 2 channels, effects loop, incredibly clean and quite DI out. These amps are not very well known in the GK line but are their top of the line amps.
The only negative thing I have to say about this amp is, it's 3 rack spaces large and not light.
If you can find one, buy it. You'll love it.
