On a budget: SD-1
Bit more cash: MXR M77
Got money to throw around: Airis Savage Drive

The SD-1 and M-77 will sound lower output than the 808, but brighter, more aggressive, and grindier. Very nasty boost pedals that I love.

The Airis Savage Drive is even more nasty, and has more output than the SD-1 and M77. Probably the best boost pedal I've ever used.

Both are based on the TV Integrated Pre.

Yeah both the Grind and 33 are clean boosts with a huge dump in the lows before 300hz. The Grid is just a flat boost of everything above 1k while I think the 33 is more high-mid focused.

But seriously, the Grind/33 is overkill for the Mark. I'd avoid it.
