This amp can produce boutique-style all-tube overdrive sounds. It also has very powerful tone controls and a Fender-sounding clean channel, so you can produce a biggest, warmest, most buttery jazz tone you could ask for. You can use the master volume feature to run the clean channel at pre-amp setting 7 or 8 and get a good Fender break-up sound for blues-oriented music.
The other thing I would say is that this amp seems to be much more powerful than the 30 watts it is rated at. I have never turned the master volume up past two at a live gig. It is LOUD.
