Great tone and flexibility were only two parts of Greg Mackie's vision for the ultimate guitar amp; portability was also key. The iron power section components of traditional vacuum tube guitar amps are heavy and bulky, but contribute the natural compression that guitar players associate as "the tube sound." The Hotwire replaces those heavy components with a discrete MOSFET power section that emulates the sag and soft-clipping of traditional analog tube components that give tube amps their distinct character.
Key word here is EMULATE.
They can emulate until they're blue in the face and this thing is still NOT going to be a real tube amp. Just ain't gonna happen.

There's just something about them real power and rectifier tubes and all them iron components.
Street price of $1500.....I'd buy a real tube amp any day over this thing at that price.
