Blammo! Model B

This pedal, apparently not made anymore, is an amazing emulator of a Sunn.

With the bass at zero it loses no low end. If you dare to push up the bass knob, instant diahrreah from the low frequency power. I don't know what the hell is in the pedal, but it's amazing. I stack my Rusty Box into it for more power. My third Blammo. They are all great.
