It's a fantastic amp. I am primarily using it as a pedal platform so the amp is set up with the V,T,M all at noon or slightly higher. Can be bright but not the way Maz's can be bright. I am using a Crazy Horse, Tiki Drive, Dr. Robery, Benson Preamp and Gain Changer through it and each of the pedals voice stands out. They were so different sounding that I compared them to the being on the clean channel of my TC-50, which apparently colors the pedals quite a bit. I LOVE the TC-50 but I was surprised how much it colored the od's vs the Jetta. Haven't even taken advantage of the effects loop on the Jetta yet. Will get around to it this week sometime. Life's just been busy.
