Built this at the request of a friend for another (mutual) friends' 30th Birthday.
Its a standard Mammoth, but I added on the inpedence control as a trimpot to a vero design by |v|ark ( http://tagboardeffects.blogspot.co.uk/ )
Also something I have done is make a trim for the LED brightness - second build I've done this on and I think its a neat little add-on.
For the graphics I used the logo of the chaps record label, and they were done by toner transfer then a thin clear coat.
Sounds like a mammoth should :)
