Blimey, mine's a far less professional looking product than either of those, but anyway... here's a Mammoth clone I've just made for my pedalboard (so no battery in this one). Based on the Fuzzdog 'Fat Furry Freak' PCB, I had most of the parts already in my spares box, so this one only cost me about £12 or so in new bits & pieces. Sounds amazing, really pleased with it. The brown dot on his trunk is a flush-mounted amber LED under the decal.
I made a bigger one in a BB box earlier in the year; that was 'Heffalump', which is why this B-sized one is Junior
EDIT: just to ease anyone's OCD... the knobs do all line up, they just weren't all zeroed for the photo.
