Amps with (built-in) fuzz?

[Dheuthymos]

I'm fully prepared for a shitstorm, but the Line 6 Bogner tube amps were criminally underrated. I usually play through the clean channel, which is plenty warm and goes well with pedals, but back when my only pedal was a BOSS phase shifter, I LOVED the fuzz setting on that amp. It's a real wooly muff sound, and the amps can be loud as hell.
