They must have thought through this little jewel carefully. The tone is very warm with well defined mid. It stays clean up to No. 6-7 where a certain grittiness begins to imply that it can do more. At 9 and up to full volume it has a controlled distortion that sounds genuine and with a lot of energy, yet focused. The tone control has everything from warm jazz to full spank on a tele. I could use this amp as a jazz amp with warm mid to a tele bridge pickup for some chick'n pick'n with a turn of the tone control. The tremolo is working on the power amp if I'm not mistaken, and that means at higher settings above 6, the tremolo ducks a bit when your playing, it is out of the way of your playing so to speak, and blooms when a chord rings out. Very musical indeed. Did I say this can be a very loud amp? It can. Perhaps this is not for the heavy distortion people out there, it is more suited for allround playing, might it be blues, jazz, pop or country. You can tell by how it acts and sounds it is quality work you have in front of you. Highly recommended
