I have a sabddi, which is supposedly a good emulator of "tube tone". I find that if I use its blend knob at 100%, it sounds like a big mid scoop+bass boost. I tried an amp that has a "tube drive" and it sounds the same way. Boomy, undefined. Like neck pickup + tone knob @0% +bass knob on the amp way up. Boom. What gives? Is the legendary "tube warmth" I hear all this clamor about just a big boomy bass boost mid scoop pillow in front of the speaker tone? Surely not... I'm confused...what happened to the midrange..
