I had a Bad Monkey for ages but then started to get annoyed with the mid-hump sound it tries to emulate and so stopped using it for a while except as a boost to a Big Muff I used to use to overcome the Muff's huge mid scoop. I'm fairly happy with my Tech 21 Double Drive again now as it's so versitile and can alter the sonic character of you amp- it can make it sound like an AC30 to a cranked Marshall and everywhere in between.

Also +1 on the BYOC Might Mouse kit, the overdrive half of it is very good
