Spent a few minutes last night playing around with my Timmy and my recently acquired MI Audio Blue Boy. Ran them into my Carr Mercury. Man, the Timmy in uncompressed mode is a killer OD pedal. Vol at 12:00, all the other knobs at 2:00. It's a thing of beauty. The Blue Boy seems to also be a great OD pedal. It does not thin my tone at all. IMO it's a medium gain pedal, not a low gain pedal. It does compress somewhat but I like (need) some compression especially when playing solos. The Blue Boy can be a little tough to dial in as small adjustments to the internal trimmers make huge differences in the tone of the pedal. IMO the Blue Boy can do the Zendrive thing pretty well. Running the the Blue Boy into the Timmy is an incredible lead tone!
