I recently purchased a Krank Rev + and found it to be a very well made piece of equipment. Solid...After a week of owning it, I returned it and bought a new TSL 100. The Krank was not a versitile amp, unless you play a lot of Pantera

. Prior to that i was using a Marshall SLX and a Fender twin ultra chorus with an A/B switch between them. So far the TSL proves to be more versitile and is a hell of a lot easier to set up.
