I had no idea the depth and control this amp had to be able to focus on any tone I could think of . I read some reviews , watch some tutorials and wondered if it could really do all that they said that it could. It's about time some one quit copying amps and made something that models the way different tubes react to voltage . No more 'cart before the horse' . It's not an amp modeler ; it's a 'Tone Machine '. With the software and the pedal it is revolutionary. From U.K. tones to U.S. tones ,it delivers and the power......unbelievable.
