I have the B7K, it's my favorite pedal for aggressive tones. It doesn't have to sound aggressive, of course, but that's its strength IMO.
I think the Blowerbox works great for subtle, low gain OD as well as the high gain stuff... but yeah, the BB would not be my first choice for vintage/warm tones.
You b@st@rds have convinced me to buy one!!
It's funny lookin', but I love the feature set. The sale makes me wonder if they're coming out with a new version, but whatever, I've been curious about this pedal for awhile and look forward to checking it out.
ha, that's what you get for hanging out around here. let us know what you think after you've given it a spin!
