I am finally looking to upgrade from my 1978 peavey combo. I play a Spector and I want an amp that matches its tone. So I always thought that tube amps have a gritty, distorted sound. Which sounds awesome on a pbass, but just not my type. So I'm looking for a clean tube amp that's not made china and has a clean, warm, deep tone. Any suggestions? Hybrids are nice too.
