mtLab - FAT Humster

Postby Crowella » 22 Sep 2017, 11:16

This is the mt'Lab FAT Humster. I don't really know much more about it other than it got some brief use by Chris Wolstenholme of Muse during the song Defector on the Drones tour. A very brief clip of the pedal was demoed on an Instagram post https://www.youtube.com/watch?v=QIMAVIDeLcg

Haven't verified the schematic yet but breadboarding the majority of it yielded positive results. There are unknown components such as the IC and Transistor due to it being scratched off, so I have made some general estimation of what it could be.

I documented it all here just in case I made some errors.

I won't lie, I'm not a huge fan of the sound of this. One thing I noticed is some of the effect leaks through when bypassed and it sounds pretty dreadful with higher gain guitars/basses.

Can you try to breaeboard a mosfet in place of q1?
Hfe reading seems a little off even for a darlington transistor!

Yeah, I might give that a go next time I touch it. Even I agree it is quite odd. It was the only part I had real difficulty working out.

I can't seem to edit the first post but I forgot to add in the other half of the DPDT switch...
